Transcribed Image Text:A mixture consists of lithium carbonate (Li,CO₂) and potassium carbonate (K₂CO₂). These react with hydrochloric acid as follows.
Li₂CO₂(s) + 2HCl(aq)-2LICI(aq) + H2O-CO2(g)
K₂CO3(s)- 2HCl(aq)
2KCI(aq) + H2O-CO₂)
When 4.377 g of this mixture was analyzed, it consumed 55.78 mL of 1.698 MHCI.
