Solid magnesium carbonate, which is insoluble, is made to react with dilute sulfuric acid. magnesium carbonate + sulfuric acid $\rightarrow$ magnesium sulfate + water + carbon dioxide The procedure for producing crystals of magnesium sulfate is given below. step 1 Place excess magnesium carbonate into dilute sulfuric acid and stir the mixture. step 2 Filter off the mixture. step 3 Heat the filtrate until the crystallisation point is reached. step 4 Allow the filtrate to cool down. Which solid is left behind as the residue removed from the mixture in step 2?
- Amagnesium carbonate
- Bsulfuric acid
- Cmagnesium sulfate
- Dwater
