$8 \ mL$ of $\frac{N}{10} \ HCl$ are required to neutralize $20 \ mL$ of $Na_2CO_3$ solution in water. The normality of the $Na_2CO_3$ solution is: (in $N$)

$10.0 \, mL$ of $0.05 \, M \, KMnO_4$ solution was consumed in a titration with $10.0 \, mL$ of given oxalic acid dihydrate solution. The strength of given oxalic acid solution is $..... \times 10^{-2} \, g / L$ (Round off to the nearest integer).

In the volumetric analysis of $HCl$,if we use phenolphthalein as an indicator,which base is unsuitable for titration?
