Write a balanced equation for the following reaction:

Sodium chloride from sodium carbonate solution and dilute hydrochloric acid.

Q 7. (b) salts A, B,C,D and E  undergo reaction (i) to (v) respectively. Identify the anion present in these salts on the basis of these reactions. Tabulate your answers in the format given below:

i) When silver nitrate solution is added to a solution of A , a white precipitate, insoluble in dilute nitric acid, is formed

ii) Addition of dilute hydrochloric acid to B produce a gas which turns lead acetate paper black

iii)When a freshly prepared solution of ferrous sulphate is added to solution of C and concentrated sulphuric acid is gently poured from the side of the test tube a brown ring is formed.

iv)  When dilute sulphuric acid is added to D a gas is produced which turns acidified  potassium dichromate solution from orange to green.

v) The addition of dilute hydrochloric acid to E produces an effervescence. The gas produced turns limewater milky but does not affect acidified potassium dichromate solution.

Choose A, B,C and D to match the description (i) to (v) below. Some alphabets may be repeated.

(A) non-electrolyte

B) strong electrolyte

C) weak electrolyte

D) metallic conductor

i) molten  ionic compound 

ii) carbon tetrachloride

iii)An aluminium

iv) a solution containing solvent molecules, solute molecules and ions formed by the dissociation of solute molecules.

v)  A sugar solution  with sugar molecules and water molecules. 

From the list of characteristics given below, select the five which are relevant to non-metals and their compounds:

A)     Ductile

B)      Conduct electricity

C)      Brittle

D)     Acidic oxides

E)      Basic oxides

F)      Discharged at anode

G)     Discharged at cathode

H)     Ionic chlorides

I)        Covalent chlorides

J)       Reaction with dilute sulphuric acid yields hydrogen

K)      1,2,or 3valence electrons

L)       5, 6, or 7 valence electrons

HCl, HNO₃,and H₂SO₄ are the formulae of three compounds. Which of these compounds has the highest boiling point and which has the lowest?

Dilute hydrochloric acid and dilute sulphuric acid are both colourless solutions. How will the addition of barium chloride solution to each help to distinguish between the two?

you enter a laboratory after a class has completed the fountain. Experiment. How will you be  able to tell whether the gas used in the experiment was hydrogen chloride or ammonia?
