The indicator used in titrating a weak acid (e.g.,oxalic acid) with a strong base (e.g.,caustic soda) solution is

The $pH$ range of methyl red indicator is .......?

Which indicator is used for the titration of $CH_3COOH$ and $NaOH$?

$50 \ mL$ of $0.1 \ M$ of a weak acid $HA$ is titrated with $0.1 \ M$ of $NaOH$. The ionization constant of $HA$ $(K_a)$ is $1.8 \times 10^{-5}$. Using the given information and from the options shown below,the best indicator for the titration of $HA$ with $NaOH$ is $....$

Phenolphthalein is not a good indicator for titrating :-

$20 \ mL$ of $0.5 \ N \ HCl$ and $35 \ mL$ of $0.1 \ N \ NaOH$ are mixed. The resulting solution will
