Solubility rules are used to predict the solubility of ionic compounds. These rules are based on the basic parameter that is size difference. a) CaCO3 According to the solubility rule, carbonates are generally insoluble in water, therefore it can be predicted that carbonate of calcium ion will be insoluble in water. b) Ca(NO3)2 According to the solubility rule, nitrates are always form soluble compounds thus we can say that calcium nitrate will be soluble in water. c) NaOH We know, sodium hydroxide is a strong base which means when they are dissolved in water, it will be completely ionized, hence sodium hydroxide is soluble in water. Hence, Ca(NO3)2 and NaOH are soluble in water, therefore, the correct option is (c).
