A solution containing methanol in water is a homogeneous mixture where methanol is dissolved in water. Methanol is miscible in water, meaning it can mix evenly with water at any proportion. This solution has a lower freezing point and higher boiling point compared to pure water. It is also flammable and toxic if ingested in large quantities.
Methanol can help increase the solubility of certain compounds compared to water alone. Testing conductivity in a mixture of methanol and water can help determine the presence of ions or charged particles in the solution, as both methanol and water can facilitate the movement of ions and enhance conductivity.
There can be an aqueous solution with methanol in it. Methanol is a pure substance, so if not mixed with other substances it is a compound.
The properties of methanol that allow it to form a homogeneous mixture with water and ethanol are its high miscibility with water and ethanol due to its polar nature. Methanol is able to hydrogen bond with water and ethanol molecules, which helps it mix uniformly with these substances, forming a homogeneous solution.
Methanol is miscible with water, which means it can mix in any proportion. When methanol is added to water, it forms a homogenous solution due to hydrogen bonding interactions between the methanol and water molecules. This allows methanol to dissolve easily in water.
Formalin is a saturated solution of formaldehyde, water, and typically another agent, most commonly methanol. In its typical form, formalin is 37% formaldehyde by weight (40% by volume), 6-13% methanol, and the rest water.

With 25ml methanol and 75ml water, there is 100ml in total. So there is 25/100 = 25% by volume methanol.
Methanol is a nonconducting solution because it does not dissociate into ions when dissolved in water. In order for a solution to conduct electricity, it must have free-moving ions that carry the electric current, which methanol lacks.
an acid is something dissolved in water to produce H+ ions.
The total moles of solute and solvent in the solution is 9.0 mol. The mole fraction of methanol would be the moles of methanol divided by the total moles. Therefore, the mole fraction of methanol in the solution is 6.0 mol / 9.0 mol = 0.67.
The final percent concentration of the solution would be approximately 12.0% methanol. This is calculated by dividing the volume of methanol by the total volume of the solution (600 ml / 5000 ml) and then multiplying by 100 to get the percentage.
To make a 100 ppm solution of methanol in 100 mL of water, you would need 10 mg of methanol. This is because 100 ppm is equivalent to 100 mg/L, and since you have 100 mL of water, you would need 10 mg of methanol (100 mg/L x 0.1 L).
The pH of a solution containing NaCl dissolved in water is neutral, around 7.
