The aqueous solution of two soluble salts are mixed to precipitate an insoluble salt. Give four different equations to support this statement.

Given the very nature of the question, you must have studied some examples. Care to share your ideas on the topic?

Following Steve's suggestion, what adding some specificity to it.

are these correct @DrBOb222 and @Steve

1) NaCl(aq) + AgNO3(aq) �¨ AgCl(s) + NaNO3(aq)
2) CaCl2(aq) + Na2CO3 (aq) �¨ CaCO3(s) + 2NaCl(aq)
3) K2SO4(aq) + Ba(NO3)2 (aq) �¨ BaSO4(s) + 2KNO3(aq)
4) Sr(NO3)2 (aq) + 2NaOH(aq) �¨ Sr(OH)2(s) + 2NaNO3(aq)

To identify four equations that support the given statement, we first need to know the specific salts involved. Could you please provide the names/formulas of the two soluble salts?
