Lab Report: How Do Different pH Levels Affect The Growth of Plants Introduction: Plant growth is affected by various environmental factors‚ and pH is one of those. The pH of soil and the water that plants receive can have an impact on whether they obtain nutrients or not. Ph impacts the chemical reactions that take place within a plant‚ if the pH of the soil or water that the plant receives is too low (acidic)‚the nutrients that the plant requires may become extremely soluble to the point where

no shell? What? You may think I am speaking about a hard boiled egg‚ but‚ no. Boiled eggs have their centers heated making the shell easily come off. Naked eggs have their shells taken off with one simple ingredient everyone has: vinegar. The acetic acid inside the vinegar strips the shell‚ calcium carbonate‚ away from the egg‚ the chemical formula is: CaCO3 (s) + 2 HC2H3O2 (aq)→Ca(C2H3O2)2 (aq) + H2O (l) + CO2 (g) (Imagination Toledo‚ 2017) Once the egg has been separated from its shell‚ the only

either use it mixed with water or vinegar. Spray it onto surfaces and leave it sit for about a day. Then scrub it and wipe it using a damp cloth. The results will not delay to appear. Use vinegar We start our list with vinegar‚ which is absolutely fantastic. It is being used for lots of other purposes due to its amazing properties. Therefore‚ if you have some affected areas in your home‚ then it is time to try this efficient and easy method. Spray some vinegar on the affected surfaces and leave

concentration. The purpose of this experiment is to show the effects of osmosis on the de-shelled egg. I hypothesize that the egg will increase in size in the vinegar and shrink in the syrup‚ staying relatively the same size in the water. Methods: Fresh boiled and shelled eggs is used in this experiment. The eggs were soaked in vinegar for up to 48 hours and no less than 24. At the end of this period the eggs are dried off and mass is recorded. The eggs are then placed in distilled water. They

Sushi Sushi is most commonly defined as a Japanese dish shaped into a roll‚ consisting of cold cooked rice dressed with vinegar‚ wrapped in seaweed and garnished with raw or cooked seafood and vegetables‚ then cut into bite-sized pieces. (dictionay.com) Although not in its most contemporary‚ present form‚ sushi has been around for a surprisingly long period of time. What began as simple‚ two ingredient rolls‚ has blossomed into multi-ingredient flavored delights. A variety of types arises from

TITLE: Toxicity Testing and Determining the LC50 INTRODUCTION: Our main objective for this experiment was to determine which three chemicals were going to be the most toxic to the brine shrimp by adding drops of vinegar‚ bleach and ammonia to the controlled water. We found that the vinegar was the most effective and the quickest. The ending results were very interesting when being compared to our hypothesis and we learned that some chemicals can react faster than others and each contains a different
