Abstract

The effects of rock salt, which is used for melting snow in the winter time, works in a variety of ways. The main reason is to aid in melting of the snow making it easier for individuals to drive their vehicles and also the sidewalk for pedestrians. Overall, the rock salt used for melting snow, works but it have some pros and cons about it, but using it wisely should be the key to its success.

Might grass growth be inhibited by salt?

Introduction

The usage of salt, (rock salt) is best used in the winter to help melt away snow from driveways, walkways, streets etc. Getting the rock salt on the lawn/yard is very dangerous, especially when the effects really show in the spring time. The effects of rock salt make the yard/lawn get brown and sometimes it dies, if not pre-treated with fertilizer or some treatment for plants.

Hypothesis:

I think that the usage of salt in the winter time affects the growth of grass in the spring time. Prediction: I predict that the grass would grow back slowly or none at all, with using salt on them in the winter time because the salt is a chemical of its own. Controlled Experimental Method: This experiment would be done in the ending of winter close to when spring is coming within a 5 week period (approximately March to April). These are the materials we would need to further the experiment: 1. Two areas to work with, a) front yard with lawn and sidewalk attached. b) Back yard with lawn, no sidewalk. 2. Journal to keep log of the observation, over the 5 week period. 3. Rock salt. 4. And of course, Snow Upon having all the necessary material, we can get the experiment started. In the front and backyard will be covered with snow, Procedures: 1. Day 1 we would spread the rock salt only in the front yard, using 2-3 cups at

    5. Salt kills the plants because the cells of plants contain water and many other dissolved substances. Since the water has a lower concentration, water molecules try to move the inside and outside the cell wall to equalize the concentration of dissolved substances in the cell, which is called osmosis. Water molecules will be sucked out of the cell by a high concentration of salt, and resultingly it causes the plants to dehydrate due to an osmosis.…

    Deicer Magnesium Chloride

    A common road salt, magnesium chloride, was analyzed in the lab to test its effectiveness as a road salt. The Van’t Hoff factor of the salt and the enthalpy of dissolution when dissolved in pure water were experimentally tested to evaluate its many characteristics as a deicer. To determine the Van’t Hoff factor, the difference of temperatures of freezing water and a solution of magnesium chloride was determined. A Van’t Hoff factor average of 2.88 was found, which is close to the ideal Van’t Hoff factor value of 3. The enthalpy of dissolution was found using calorimetry. Various amounts of magnesium chloride were added to water finding the heat of reaction for each trial. Depending on how many moles of magnesium chloride were present in each solution, the enthalpy of dissolution was then calculated which gave an average of -151.45 kJ/mol making the reaction exothermic. Magnesium chloride was compared to three other road salts to determine which of the road salts was the best for Minnesota’s winter roads. Due to the ability to lower the freezing point of water, the substantial value of enthalpy change, the least cost effective, and non-harmful effects to the environment it makes the best chloride deicer out of potassium chloride, sodium chloride, and calcium chloride.…

    Salt and Grass Growth

    • 873 Words
    • 4 Pages

    In the winter, salt is spread daily on the driveway in order to melt snow and ice. In the spring, when the grass begins to grow, it is noticed that there is not any grass growing about 3 inches from the driveway. In addition, the grass appears to be growing slower about 1 foot from the driveway. Prior to an experiment being conducted, it must be determined what the salt compound being applied to the driveway is made up of in order to get a clear picture of how it may be affecting the grass growth. Salt is sodium chloride that occurs naturally on earth as mineral halite. When mineral halite evaporates, it turns into salt lakes. The chemical compound is NaCl with 60.663% elemental chlorine (Cl) and 39.337% sodium (Na). Salt crystals are cubic in form and can be modified by temperature. Salt that is commonly used for deicing is rock salt also known as halite. Rock salt’s crystals are much larger than the common table salt’s crystals ("What is salt?," 2013).…

    Secondly, not only does the salt that cities use pose a threat to our aquatic ecosystems, it also poses a huge threat to our vegetation as well. When salt dissolves in water, it replaces important nutrients that all plants need to survive. The sodium ions separate from the chloride ions and the nutrients such as potassium, calcium, and magnesium, nutrients that the plants need to survive, are replaced by the salt ions. When this happens, it can disturb the photosynthesis of the plant, or cause the plants to become stressed out. If plants continue to not receive nutrients, and continue to be stressed out, it typically leads to the death of that plant.…

    Essay On Salt Water

    • 416 Words
    • 2 Pages

    People have been using salt since 6050 bc.We have used it for seasoning, preservation, and in the last century for lowering the freezing point of water(History of Salt). In pure water 0 degrees celsius is the normal freezing point of water. Ice will melt just as fast the water will freeze. You won't see the melting and freezing processes as long as they are balanced and equal. Adding salt or any foreign substance to the water upsets the fragile equality between freezing and melting. Less of the water molecules reach the surface of the ice in an amount of given time. The melting rate isn't changed by the salt, so melting is going to happen faster than the freezing. This makes the ice melt(Frederick A. Senese, Why can adding salt to ice water make the ice melt slower?).…

    Small variations in salinity can make a monumental difference on the water cycle and the ocean circulation. Trouble can also arise when saltwater gets transferred onto the earth. That can damage the soil and wreck habitats! There are two types of salinity, primary and secondary salinity. Primary salinity is when water or soil naturally has a high amount of salt in it, like in a salt lake. Secondary salinity is caused by humans. It can be caused by clearing too much land, which makes the groundwater rise to the surface and the salts inside dissolve into the soil.Secondary salinity has two main forms of which it happens. The first is dry land salinity; when more water enters the groundwater than is taken out, so it can enter vegetation on land and become absorbed by the soil. There is also Irrigation salinity; (Irrigation is the act of flowing water over crops to nourish them), salts can collect in the topsoil under the irrigation. Too much irrigation or poor water are the main causes of…

    “All soil contains salts, many of which are essential nutrients for plants. Salinity occurs when soluble salts (usually NaCl) are elevated in soil and water. Every continent is affected by salinized soil and water; approximately 7% of the world’s land area.” (Nerissa Hannink, 2005).…
