<h3>Does methanol keep things from freezing?</h3>

Methanol is an extremely effective anti-freeze agent. Even little amounts can have a significant effect on freezing temperatures. Deschamps, Mousis, Sanchez-Valle, and Lunine investigated the impact of methanol concentrations of a few percent and discovered that they might play a major role in the formation and preservation of a subsurface ocean.

The effects of pressure on pure ice and pure methanol have been widely researched, but the behaviour of water-methanol mixes has not been as thoroughly explored. We intend to conduct a series of experiments to investigate how various spots on the methanol-water phase diagram change under pressure

<h3>What is titration reaction?</h3>

Titration is a chemical analysis procedure that determines the amount of a sample's ingredient by adding a precisely known amount of another substance to the measured sample, with which the desired constituent reacts in a specific, known proportion.

Make use of the titration formula.

The formula is molarity (M) of the acid x volume (V) of the acid = molarity (M) of the base x volume (V) of the base.

if the titrant and analyte have a 1:1 mole ratio. (Molarity is a measure of a solution's concentration represented as the number of moles of solute per litre of solution.)

26 x 1.8 = 40 x M

M = 26 x1.8 /40

M = 1.17

The Molar concentration of your analyte solution is 1.17 m
