`50ml N//10 NaOH` solution is mixed with `50 ml N//20 HCl` solution. The resulting solution will
`(a)` Turns phenolphthalein solution pink`" " (b)` Turns blue litmus red
`(c )` Turns methyl orange red `" "(d) [H^(+)] & [OH^(-)]`

A

only `(a)` is correct

B

`(a) & (b)` are correct

C

`(a) & (d)` are correct

D

all are correct

Text Solution

Verified by Experts

The correct Answer is:
C
Since solution is basic in nature hence,
`[H^(+)]lt[OH^(-)]` and phenolphathalein will turn the solution pink, Ans `(a) & (d)`.
