to tell about WATER water is the most imp thing on earth.without water no life.We take it for granted‚ we waste it‚ and we even pay too much to drink it from little plastic bottles. And still‚ today‚ nearly 1 billion people in the developing world don’t have access to it. Clean‚ safe drinking water is scarce. It is the foundation of life‚ a basic human need. Yet today‚ all around the world‚ far too many people spend their entire day searching for it. Simply put‚ water scarcity is either

Brooke Thomas September 13‚ 2012 Separating Salt and Sand Lab Report Separating components of a mixture of salt and sand and calculate the mass of each. Salt is soluble and sand will sink to the bottom‚ you can separate the rest with filtering and distillation (boiling). If salt and sand are a mixture‚ then we can separate them by physical processes.

determine how an excess amount of liquid‚ which was water‚ Gatorade and wine in this case‚ along with an excess amount of solute‚ which was the 7g NaCl pill‚ would affect the kidneys and the osmolarity of urine. Measurements of urine volume‚ specific gravity and chloride concentrations were recorded in order to investigate this. Our hypothesis stated that the volume of urine would increase for all groups other than the group drinking 80 ml of water along with taking a 7g. This portion of the hypothesis

article “Sea Salt Around the World is Contaminated by Plastic” researchers discover that microplastics in sea salt from around the US‚ Europe‚ and China. This also proves that plastic pollution is pervasive in the environment. Research proved that tiny plastic particles have been found in our sea salt. This is dangerous because it means that microplastics are entering our daily food chain through the salts in our diets. Scientist believe that most of the contamination comes from water bottles and

My Science Project Can water float on water? My Prediction I predict that water can’t float on top of water. Simply because it sounds impossible‚ but it will be interesting to find out if however it is possible. The Experiment First‚ I found two 1litre bottles and marked one with ‘+ salt’ and the other with ‘fresh’. I then went on to add red food colouring to the fresh bottle and yellow to the + salt bottle. The reason for doing so was to establish which ones were which and see if they

Roasted Salt-and-Vinegar Potatoes From Cook’s Country | August/September 2012 Share Email Print Shopping list Add to favorites WHY THIS RECIPE WORKS: Cooking small red potatoes in a super-saturated salt solution creates an incredibly creamy‚ well-seasoned potato interior. After the potatoes are par cooked‚ we “smash” them to expose some of the potato flesh‚ brush them with malt vinegar‚ and roast them on a well-oiled sheet pan until the… read more Roasted Salt-and-Vinegar Potatoes Making crispy

The litmus paper and the pH probe determined the salt solutions’ pH levels. When the blue litmus paper was dipped into ammonium chloride‚ the paper was changed to red whereas the red litmus paper stayed the same indicating that the solution was acidic. PH levels shown through pH probe also ranged between 5.5 to 6.0. Yet when in the presence of sodium acetate blue litmus stayed blue whereas red litmus turned blue‚ indicating its basicity. pH probe also showed the solution’s pH varied between the

Epsom salt have many uses‚ including use as bath salts‚ as a laxative and as a plant nutrient. Epsom salt contains hydrated magnesium sulphate which has the formula MgSO4.xH2O. Experiment to find the value of x in a pure sample of hydrated magnesium sulphate. The method i will use is heating a known mass of magnesium sulphate to remove the water of crystallisation. x is found by weighing before and after heating to find the mass of the water then using the moles calculations to find x.

Water pollution Water pollution is the contamination of water bodies . Mostly water pollution occurs in lakes‚ rivers‚ oceans‚ aquifers and groundwater. Water pollution occurs when pollutants are directly or indirectly discharged into water bodies without adequate treatmentto remove harmful compounds. Type of water pollutions There are many types of water pollution because water comes from many sources. Here are a few types of water pollution: 1. Nutrients Pollution Some wastewater‚ fertilizers
