When methanol CH3OH is dissolved in water a nonconducting solution results When acetic acid CH3COOH dissolves in water the solution is weakly conducting and acidic in nature?
Methanol (CH3OH) is a nonelectrolyte, meaning it does not ionize in water, resulting in a nonconducting solution. In contrast, acetic acid (CH3COOH) is a weak acid that partially ionizes in water, producing hydrogen ions (H⁺) and acetate ions (CH3COO⁻), which allows the solution to conduct electricity and exhibit acidic properties. The difference in conductivity and acidity between the two solutions is due to their distinct behavior in water regarding ionization.
What is the final percent concentration of the solution when 600 ml of 100 percent methanol added to 4400 ml of water?
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.
What is the percent by volume of 25 ml of methanol in 75 ml of water?
With 25ml methanol and 75ml water, there is 100ml in total. So there is 25/100 = 25% by volume methanol.
How much methanol needed to make 100 ppm solution in 100ml water?
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).
Is calcium nitrate soluble in methanol?
Being an ionic inorganic salt, PbNO3 is soluble in water which is similar in structure as methanol (CH3OH) but we must remember that water is inorganic in nature unlike methanol which is a typical organic compound. From our knowledge of organic compounds we may simply predict that lead nitrate is insoluble in methanol.
When methanol CH3OH is dissolved in water a nonconducting solution results. When acetic acid CH3COOH dissolves in water the solution is weakly conducting and acidic in nature.?
Methanol does not dissociate into ions when dissolved in water, making it a nonconducting solution. Acetic acid, on the other hand, partially dissociates into ions in water, forming H+ ions which conduct electricity and contribute to the solution's acidity.

Is methanol part of an aqueous solution?
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.
What is the mole fraction of methanol in a solution that contains 6.0 mol of methanol and 3.0 mol of water?
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.

Why was methanol an appropriate solvent to precipitate polystyrene?
Methanol is used to force polystyrene OUT of solution. So the simple answer is: you can't. But, there is probably an extreme temperature or pressure that allows polystyrene to remain in solution with methanol present.
What is the percent by volume of 25 ml of methanol in 75 ml of water?
With 25ml methanol and 75ml water, there is 100ml in total. So there is 25/100 = 25% by volume methanol.
What are the properties of a solution containing methanol in water?
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.
How does methanol react with water?
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.
How much methanol needed to make 100 ppm solution in 100ml water?
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).
What is the molarity of methanol and ethanol?
The molarity of methanol (CH3OH) and ethanol (C2H5OH) depends on the concentration of each substance in a given solution. To calculate the molarity, you need to know the amount of the solute (methanol or ethanol) in moles and the volume of the solution in liters. The formula for molarity is moles of solute divided by liters of solution.
Why is methanol strong electrolyte?
Methanol is a strong electrolyte because it dissociates almost completely in solution to form charged particles called ions. This is due to the presence of polar covalent bonds in its molecular structure which allow for the separation of positive and negative ions in solution. As a result, methanol is able to conduct electricity efficiently in aqueous solution.
