efficient‚ cheap (but not as cheap as the old battery acid). The chemistry is relatively simple‚ rust (iron oxide) is Solubilised by the acid (ammonium ion is also acidic) and citrate ion coordinates to the iron-forming soluble iron citrate. Citric acid has an advantage over some other acids‚ because it is less corrosive‚ not as dangerous to the environment‚ while remaining efficient‚ cheap (but not as cheap as the old battery acid). The chemistry is relatively simple‚ rust (iron oxide) is Solubilised by

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.
