Question

# $$Na_2CO_3$$ can be manufactured by Solvay's process but $$K_2CO_3$$ cannot be prepared because:

A
K2CO3 is more soluble than Na2CO3
B
K2CO3 is less soluble than Na2CO3
C
KHCO3 is more soluble than NaHCO3
D
KHCO3 is less soluble than NaHCO3a
E
None of the above

Solution

## The correct option is B $$K_2CO_3$$ is less soluble than $$Na_2CO_3$$$$Na_2CO_3$$ can be manufactured by Solvay's process by the reaction of Nacl and $$CaCO_3$$ which gives insoluble precipitate of  $$Na_2CO_3$$.But $$K_2CO_3$$ cannot be prepared because as it is soluble and can't be separated out.Hence option B is correct.Chemistry
