FREE Expert Solution

In this problem, we are asked to determine the precipitate or the lack thereof.


The given reactions are:

a) CaCl2(aq) + K2CO3(aq) → CaCO3 + 2KCl

i) CaCO3

  • Carbonates (CO32-) are insoluble except when with Group 1A ions (Li+, Na+, K+, etc.) and ammonium ion (NH4+)
  •  CaCO3insoluble → precipitate → CaCO3(s)
