Answer 1

A)

Products are NH4Cl and K2CO3

Ammonium Salts are soluble

So, NH4Cl is soluble

Salt of alkali metals are soluble

So, K2CO3 is soluble

So, no precipitate form

B)

Products are Sr(NO3)2 and C2H3O2Na

Salt of NO3- are soluble

So, Sr(NO3)2 is soluble

C2H3O2Na is soluble.

So, no precipitate form

C)

Products are Ca(OH)2 and NaBr

Ca(OH)2 is strong base and hence soluble

Salt of alkali metals are soluble

So, NaBr is soluble

So, no precipitate form

D)

Products are Ca(NO3)2 and AgI

Salt of NO3- are soluble

So, Ca(NO3)2 is soluble

AgI is not soluble. This is precipitate

Answer: D
