Explanation:
You can predict its acidity (pH).
The formula for pH is: pH = log { 1 / [H+] } = log { 1 / (1*10^-12) }
=> pH = log {10^12} = 12.
Remember that acids have pH between 1 and less than 7 and basic compounds have pH greater than 7 and less than 14.
So, you can predict that this product is a base (alkaline).
Propanal will form silver mirror upon heating with Tollen's reagent while propanoic acid will not respond.
