You are provided with aqueous solutions of three salts - A,B and C,2-3 drops of blue litmus solution, red litmus solution and phenophtanlein were added to each of these solution in separate experiment. The change in colour of different indicators were recorded in the following table :

On the basis of above observation, identify A,B, and C from the following options :

Options

A. `A=NH_(4)CI,B=NaCI,C=CH_(3)COONa`
B. `A=NH_(4)CI,B=CH_(3)COONa,C=NaCI`
C. `A=NaCI,B=NH_(4)CI,C=CH_(3)COONa`
D. `A=CH_(3)COONa,B=NH_(4)CI,C=NaCI`

Answer

C

Explanation

A neutral salt solution does not change with blue litmus solution, red litmus solution and with phenophthalein solution. An acidic salt solution turns blue litmus to red litmus solution brings no change in red litmus solution as well as in phenophthalein solution.
Basic salt solution turns red litmus to blue litmus solution and also turns phenophthalein solution pink,
