WebIf we add a strong acid or strong base to water, the pH will change dramatically. For instance, adding a strong acid such as HCl to water results in the reaction HCl + H 2 O → H 3 O + + Cl-.In other words, the proton (H +) from the acid binds to neutral water molecules to form H 3 O + raising the concentration of H +.The resulting large concentration of (H +) … WebQUESTION 1 Consider the titration of 20.00 mL of 0.150 M NH3 with 0.250 M HCI.
