Write the balanced chemical equation : Lead nitrate solution is added to sodium chloride solution

Name the method used from the list:

A : Simple displacement
B : Neutralization
C : Decomposition by acid
D : Double decomposition
E : Direct synthesis

For preparation of the following salts –

(i) Sodium nitrate

(ii) Iron (III) chloride

(iii) Lead chloride

(iv) Zinc sulphate

(v) Sodium hydrogen sulphate.

Select the word/s given below which are required to correctly complete the blanks — [ammonia, ammonium, carbonate, carbon dioxide, hydrogen, hydronium, hydroxide, precipitate, salt water] :

(i) A solution M turns blue litmus red, so it must contain (i) …………… ions ; another solution O turns red litmus blue and hence, must contain, (ii) …………… ions.

(ii) When solution M and O are mixed together, the prod­ucts will be (iii) …………… and (iv) …………… .

(iii) If a piece of magnesium was put into a solution M,(v) …………… gas would be evolved.

Give a suitable chemical term for:

(i) A salt formed by incomplete neutralisation of an acid by a base.

(ii) A definite number of water molecules bound to some salts.
