At the equivalence point of the titration of acetic acid with sodium hydroxide at 298 K, the pH is

Answer: D

At equivalence only sodium acetate remains. Acetate hydrolyses:

CH X_{3} COO X^{-} + H X_{2} O CH X_{3} COOH + OH X^{-}

, so the solution is basic and pH

> 7

Methyl orange (colour change range pH 3.1 to 4.4) is a suitable indicator for the titration of NEET level
A weak acid HA (K_a = 1x10^-5) is half neutralised by NaOH. The pH of the solution is NEET level
25.0 mL of 0.100 M acetic acid (K_a = 1.8x10^-5) is titrated with 0.100 M NaOH. The pH after adding 10.0 mL of NaOH is JEE Main level
25.0 mL of 0.10 M HCl is mixed with 20.0 mL of 0.080 M NaOH. Use log 2 = 0.301. The pH of the mixture is closest to JEE Main level
25.0 mL of 0.10 M acetic acid is titrated with 0.10 M NaOH (K_a = 1.8x10^-5). Indicator ranges: methyl orange 3.1-4.4; methyl red 4.2-6.3; b... JEE Main level
20.0 mL of 0.10 M formic acid (K_a = 1.8x10^-4) is titrated with 0.10 M NaOH. Calculate the pH at the equivalence point at 298 K, using pH =... JEE Main level
