Since the density of pure NaOH is 1.5 times that of pure HCl and the volumes (and volume percent) are equal, the mass (and moles) of NaOH will be 1.5 times that of HCl.
NaOH is in excess.
Therefore, the resultant solution will be basic.
NaOH is in excess.
Therefore, the resultant solution will be basic.

Explanation:
Given:
- Equal volumes of 10% (v/v) HCl and NaOH solutions are mixed.
- Density of pure NaOH is 1.5 times that of pure HCl.
Calculating Concentration of HCl and NaOH:
- 10% (v/v) HCl means 10 ml of HCl in 100 ml solution.
- 10% (v/v) NaOH means 10 ml of NaOH in 100 ml solution.
Calculating Density:
- If the density of pure NaOH is 1.5 times that of pure HCl, the density of NaOH is greater.
Reaction between HCl and NaOH:
- HCl is a strong acid, and NaOH is a strong base. When they react, they form water and a salt.
- The reaction between HCl and NaOH results in the formation of water and NaCl (salt).
pH of Resultant Solution:
- Since equal volumes of 10% HCl and NaOH solutions are mixed, the acid and base will neutralize each other.
- The resulting solution will be basic due to the excess of NaOH from the reaction.
Therefore, the resultant solution will be basic.
