hydrated salt in order to determine the percentage of water inside of this hydrated salt. We heated up the salt in order to boil off the water‚ which allowed us to find the weight of the CuSO4 by itself. By comparing this final weight with the original weight and subtracting the difference‚ we were able to compile data about how much the weight of the hydrated salt decreased as the water gradually boiled away. In doing so‚ we were able to find the total weight of the water in the hydrated salt by subtracting

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.

separate salt‚ sand and iron filings from each other in a mixture‚ to figure out the percentage of each component in the original mixture? Background Research: In this Investigation‚ I will be separating sand‚ salt‚ iron fillings in a mixture and finding their percentages. Iron is a magnetic solid which is incapable of being dissolved in water. Salt is a non-magnetic solid which is capable of being dissolved in water. Sand is a non-magnetic solid which is incapable of being dissolved in water. I used

Effect of Temperature on Salt Diffusion Rates and it’s Relation to the Human Body Hypothesis: Ordinary table salt is known to dissolve easily in water. Dissolving or diffusion is the spreading of particles in another substance. This is seen when smoke from a chimney diffuses in the air around it‚ or when dropping coloring in water. When NaCl‚ sodium chloride‚ or otherwise known as ordinary table salt is combined with water the separate salt and water molecules will be attracted to each other

Salt i. scientific - I think that scientifically building this on the salt marsh is unacceptable. We know that there are thousands of organisms inhabiting it‚ and they`d all be destroyed during the process. The benifits are endless of a salt marsh‚ but include the fact that it is protecting us from possible floods‚ seeing as we live beside the ocean‚ and a river. Filtering our water‚ and like I mentioned‚ it`s home to many organisms. ii.économique - Economically the benifits of this project

experiment explores how salt and sugar affect the melting rate of ice in water. Research Questions: * Does adding salt to ice and water slow down‚ speed up‚ or not change the rate the ice melts in the water? * Is salt the only substance to have this effect? What about sugar? Knowing how to speed up the melting rate of ice is very important information for anyone who needs to de-ice roads or driveways after a winter storm. While it seems simple‚ adding salt to ice water actually activates two

Hypothesis: Temperature of water affects the time taken for salt to dissolve Introduction: In this is will be doing a coursework an experiment in which I will be trying to prove my hypothesis? I will do a set of trial experiment and a main one which I will be trying different temperature‚ which I can prove that this will work and to make sure I get hang of it when I do my real experiment. I will also draw a set of graphs in which I can show which can show if this proves my hypothesis. Important

3. Why are stabilisation salts added to evaporated or condensed milks prior to heating? The heat stability of milk is of tremendous importance in the successful processing of milk and the manufacture of most dairy products. Appropriate application of heat becomes necessary not just for destruction of spore-resistant micro-organisms but also for the preservation of the most desirable product characteristics. However‚ milk should not coagulate on heating. Heat coagulation is chiefly caused by de-stabilization
