Explain a mixture consists of lithium carbonate

Reference no: EM13290716

A mixture consists of lithium carbonate (Li2CO3) and potassium carbonate (K2CO3). These react with hydrochloric acid as follows.

Li2CO3(s) + 2HCl(aq)2LiCl(aq) + H2O + CO2(g)

K2CO3(s) + 2HCl(aq)2KCl(aq) + H2O + CO2(g)

When 8.982g of this mixture was analyzed, it consumed95.12mL of2.043M HCl.
