100 ml solution having 0.2 M HA (weak acid, `K_(a), = 1.0x10^(-5) )` and 0.2 N NaA, 200 ml of 0.1 M NaOH has been added. Furthermore, diluted to IL. Which of the following statement is correct?

Initially, the solution has pH equal to 5, that is before addition of NaOH

In the final solution, the concentration of `[OH^(-)]` is `10^(-9)` M.

After the addition of NaOH, the pH of solution increase by four units.

After the addition of base, the solution losses buffering action and can be restored after the addition of acid.

100 ml solutions having 0.2 M HA (weak acid , Ka = 1.0 xx 10^(-5)) and 0.2 N Na A . 200 ml of 0.1 M NaOH has been added . Furthermore, dilute to 1L . Which of the following statement is correct ?

Initially , the solution has pH equal to 5, that is before additions of NaOH

In the final solution , the concentration of `[OH^(-) ] is 10^(-9) ` M.

After the addition of NaOH , the pH of solution increase by four units.

After the addition of base, the solution losses buffering action and can be restored after the addition of acid.

its 0.01 M Solution has `PH gt 4.3`

its 0.01 M solution has `pH lt 4.3 `

its 0.01 M solution degree of dissociation is less than in 0.1 M solution

its 0.01M solution degree of dissociation in less than in 0.1 M solution

its 0.01 M Solution has `PH gt 4.3`

its 0.01 M solution has `pH lt 4.3 `

its 0.01 M solution degree of dissociation is less than in 0.1 M solution

its 0.01M solution degree of dissociation in less than in 0.1 M solution
