Hi, I've been set a whole load of homework of which I absolument null. I'm allowing myself to ask for help on this one question because I don't have a clue, have been searching online for aaages and can't find the answer. If I don't ask then I'll end up giving up and failing GCSE chemistry. I really need help, my passing is in your hands!!! There are four main methods of making salts: A Acid + metal B Acid + insoluble base C Acid + alkali D Solution of salt A + solution of salt B a. A student wanted to make some sodium sulfate. i. which method would be the best one to use? ii. why? iii. name the reactants you would use. iv. write a word equation for the reaction. b. Another student wanted to make some magnesium carbonate i. which method would you use for this salt? ii. why? iii. name the reactants you would use iv. write a word equation for the reaction. Please help!!!!! I've got latin to do next :S xx
