100 ml of 0.1 M NaCl and 100 ml of 0.2 MNaOH are mixed. What is the change in pH of NaCI solution ?

Text Solution

Verified by Experts

The correct Answer is:
6
pH of 100 ml of 0.1 M NaCl = 7
` [OH^(-) ] (100xx 0 + 100 xx 0.2 )/( 200) =(20)/( 200) =(1)/( 20 ) = 0.1`
`pOH =1 , pH =13`
change in pH of NaCl =` 13 - 7= 6`
