alcohols have methyl groups, ethyl groups ect... attached to the alcohol. Carbon and its hydrogens are considerd electron donating groups (because they are not electronegative like F, O or N); therefore they donate part of their electric charge toward the oxygen on the alcohol making that oxygen less able to distribute the electron from the lost hydrogen. Meanwhile, water can lose a hydrogen and does not contain any electron donating groups (such as Carbon) and the oxygen is better suited to distribute the extra electrons from the lost hydrogen. think about it... if carbon is donating part of its electrons to oxygen in an alcohol, there is less room for that oxygen to take on the electrons from a lost hydrogen vs water.
Generally, alcohol is considered neutral. Like water, however, it can behave very weakly as both an acid and its base. Ulike water, though, its basic properties are very slightly stronger than its acidic properties.
Mn2O7 is more acidic than MnO2. This is because Mn2O7 is a peroxide compound that contains more oxygen atoms and can release more H+ ions when dissolved in water, making it a stronger acid than MnO2.
Water has a higher surface tension than rubbing alcohol, which allows it to form a more cohesive droplet that can hold together better on the surface of a penny. Additionally, water is more polar than rubbing alcohol, leading to stronger adhesive forces between the water molecules and the penny's surface. This results in water being able to "stick" and accumulate more effectively than rubbing alcohol.
Regular water has stronger intermolecular bonding due to its hydrogen bonding capability, which is more pronounced than in soapy water or an alcohol-water mixture. Soapy water contains surfactants that disrupt these hydrogen bonds, while an alcohol-water mixture has weaker hydrogen bonds compared to pure water due to the presence of alcohol molecules that interfere with water's cohesive forces. Therefore, regular water exhibits the strongest intermolecular bonding among the three.
Water mixed with alcohol is lighter than fresh water because alcohol is less dense than water. When alcohol is added to water, the overall density of the mixture decreases due to the lower density of alcohol, making the mixture lighter than fresh water.
Methyl alcohol (methanol) is actually not the most acidic compound. Stronger acids, such as hydrochloric acid (HCl) or sulfuric acid (H2SO4), have lower pKa values and are more acidic than methanol. Methanol is a weak acid compared to these stronger acids.
Generally yes, water has a higher Ka value than most alcohols including beverage alcohol.

Acetic acid is a stronger acid. Ethanol is an alcohol which is slightly acidic but usually neutral in nature.
Alcohol: C6H13OH (hydroxy-hexane) Phenol : C6H5OH (hydroxy-benzene) Phenolic -OH is acidic (4x stronger than vinegar) where s alcoholic -OH isn't acidic at all; both are NOT ionic or alkaline (OH-)
Water is stronger than rock.
Hydrogen peroxide is a bit more acidic (proton donor) and a much stronger oxidant (electron acceptor) than water.

No. Alcohol evaporates faster than water, so if anything, it gets weaker.

A solution with a pH lower than that of distilled water would be acidic. This could be achieved by adding an acid such as hydrochloric acid or sulfuric acid to water. Acidic solutions have a pH below 7, with the lower the pH, the more acidic the solution will be.
