WebUsing a pipette and safety filler, transfer 20 cm 3 (or 25 cm 3) of the sodium hydroxide solution into the cup, and measure the steady temperature. Using the burette, add a small portion (3–5 cm 3) of dilute hydrochloric acid to the solution in the cup, noting down the actual volume reading. WebJul 31, 2024 · Molarity is a temperature-dependent parameter. The volume of a solution increases with an increase in temperature diye to increase in intermolecular spaces and vice versa. Hence, molarity is affected by temperature change. As Molarity (M) is defined as the number of moles of solute (n) divided by the volume (V) of the solution in liters.
