Question
what happens to PH of NH4OH solution when NH4Cl crystals is added to it?
Solution
When NH4Cl crystals are added to an NH4OH solution, the following steps occur:
- NH4Cl crystals dissociate into NH4+ and Cl- ions.
- NH4+ ions react with OH- ions from NH4OH to form water (H2O) and NH3 gas (ammonia) according to the equation: NH4+ + OH- → H2O + NH3.
- The formation of NH3 gas leads to a decrease in the concentration of OH- ions in the solution.
- Since pH is a measure of the concentration of OH- ions in a solution, the decrease in OH- ions results in a decrease in the pH of the NH4OH solution.
- Therefore, when NH4Cl crystals are added to an NH4OH solution, the pH of the solution decreases.
