Question

What will be the final concentration when equal volumes of 10% (v/v) and 20% (v/v) ethanol solutions are mixed?​

Answer 1

Explanation:

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.
