1.	i. Classify the following reactions into different types:a. AgNO3(aq) + NaCl(aq) →AgCl(s) + NaNO3(aq)b. CaO(s) + H2O(l) → Ca(OH)2(aq)c. 2KClO3(s) →2KCl(s) + 3O2(g)ii. Which of the above reaction(s) is/are precipitation reaction(s)? Why is a reaction called precipitation reaction?
Answer» i. a. Double displacement reaction b. Combination reaction c. Thermal decomposition reaction ii. Reaction (a) is a precipitation reaction because precipitate of silver chloride is formed as the product. When a product of a chemical reaction is obtained in the form of a precipitate (insoluble substance), then that reaction is called as precipitation reaction.
