Explanation Flask that is used for the KOH solution contains a small amount of distilled water in it. This does not make a difference as potassium hydroxide is the analyte while hydrochloric acid is the titrant. The presence of small amount of distilled water in the flask only results in dilution of the solution and there will not be any change in moles of potassium hydroxide. Hence, the event in option (a) does not have any effect. Buret contains the hydrochloric acid solution. If this is not dried and a small amount of distilled water is present in it, then the consumption of hydrochloric acid will be more in order to neutralize the potassium hydroxide. This is because hydrochloric acid is the titrant. Due to this the concentration of the analyte potassium hydroxide will be too high. Hence, the event in option (b) has an effect. Buret contains the hydrochloric acid solution. If this is not dried and a small amount of oil is present in the side walls, the water drops gets stick to it as the level falls
