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

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

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

of purified water again. Due to the people of the United States drinking billions of gallons of water daily‚ the amount of purified water we drink is starting to run out which is causing a problem already. Psychological studies have shown humans still don’t accept water being reused even after knowing the water is purified and perfectly clean. Advocates are still against ultraviolet machines being used to clean and purify water. While some people believe that drinking recycled water is both repulsive

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.
