Question
Which molecule, when added to a solution, would give the solution the highest pH? (3 points)HClH2SO4KOHH2O
Solution
The molecule that would give the solution the highest pH when added is KOH.
Here's why:
-
pH is a measure of the hydrogen ion concentration in a solution. The lower the concentration of H+ ions, the higher the pH.
-
HCl (hydrochloric acid) and H2SO4 (sulfuric acid) are both strong acids. When they dissolve in water, they increase the concentration of H+ ions, which would lower the pH of the solution.
-
H2O (water) is neutral, with a pH of 7. Adding it to a solution would not significantly change the pH.
-
KOH (potassium hydroxide) is a strong base. When it dissolves in water, it produces OH- ions. These ions can react with H+ ions to form water, thereby decreasing the H+ ion concentration and increasing the pH.
So, KOH would give the solution the highest pH.
