PH scale, PH of strong acids and strong bases

Question

Statement I : In the acid – base titration involving strong base and weak acid, methyl red can be used as an indicator.
Statement II : Methyl red does not changes its colour in the pH range 4.2 to 6.3.

Easy

A

Statement I and II are correct
B

Statement I is correct and Statement II is incorrect
C

Statement - I is incorrect and Statement II is correct
D

Both statement - I and statement - II are False

Solution

During an acid-base titration involving a strong base and weak acid, the P^H of the system will vary from around 6 to 13. This range of P^H should considerably overlap with the color change range of the indicator, then only the indicator will suitable point the end point. Range of P^H in which methyl red changes color is 4.4 to 6.2.
