100 mL of HCI + 35 mL of NaOH, colour of methyl orange in the solution will be

A

Red

B

Yellow

C

Can't predicted

D

Methyl orange is not a suitable indicator

Text Solution

Verified by Experts

The correct Answer is:
A
According to the question, 35ml of NaOH will neutralise 35ml of HCl and since, in the mixture of these solutions the volume of HCl is much higher, so, the resultant mixture would be acidic in nature.
`HCl_((aq)) +NaOH_((aq)) hArrNaCl_((aq)) +H_(2)O_((l))`
` :. ` Methyl orange would impart a red colour to the acidic mixture of solutions.
