It increases H+ concentration and decrease pH according to pH = -log[H+]
If acid is strong (it doesn't have a Ka>1) it will be ionized 100%.
If it's not >1 it will be ionized according its Ka. It's called weak and pH is not so strongly affected as if it were strong
A base has the effect of increasing pH. So water, which in a pure state has a pH of 7, might increase its pH to 9 if a base were added - the exact amount of increase would depend uppn both the specific chemical used, and the concentration of the resulting solution.
The pH of an acid solution is reduced when acid is added to water.
This has to do with chemical equilibrium. When an acid is placed into water, it dissociates, or breaks apart into it's component ions. For strong acids like HCl, 99.997% of the acid breaks apart, so it's considered to break apart 100%. The amount of H+ (sometimes called H3O+ or hydronium) determines how acidic a solution is.
The Ph will decrease. This is because water has a neutral Ph value of 7 so if an acid which has a lower Ph value than water is added to it, the Ph will decrease
It rises from below 7 (acidic) until 7 is reached (= pH of pure water, at infinite dilution)
Nothing. Since water is neutral, the pH remains the same.
The pH number will go to 7, same thing that will happen if an acid is added to an base.
The presence of an acid lowers the pH of the solution in water.
Pure water has a pH close to 7. When you add an acid (solution with a pH less than 7) to pure water, the pH will become less than 7.
The presence of an acid reduces the pH.
When an acid (any) is added the H+ concentration goes up, and the pH goes down.
H3O+ (or just H+)
The premise of this question is incorrect. When NaOH is added to water the hydroxide concentration increases. NaOH is a base. If a substance decreases hydroxide concentration it would be an acid.
When H2O is added to acid it begins to boil due to the strong reaction between the acid and the Base (the water). Don´t add H2O to acids add acid to water. Water is both an acid and a base, when it is reacting with acid it becomes base and reacts with base it becomes acid.
The added ethanol will not affect the pH whatsoever, due to the fact that ethanol cannot donate hydrogen ions or accept them. The added volume will, however, not affect the molar mass of the acid that you will report from the analyses. You use the volume of base that is used to titrate the acid to find the moles of acid and base at stoichiometric point so the added volume will not affect the molar mass.

Hydrogen ions will form and the pH of the water will increase.
An Arrhenius acid is a substance that when added to water increases the concentration of H+ ions. When it is added to water, it loses its hydrogen ion, which combines with water molecules to form hydronium, H3O+. Hydrochloric acid is an example of an Arrhenius acid. HCl + H2O ---> H3O+ + Cl-
It will be an aqueous acetic acid solution. normally water is added in order to decrease the concentration of an acid & gives the diluted form of it.
The premise of this question is incorrect. When NaOH is added to water the hydroxide concentration increases. NaOH is a base. If a substance decreases hydroxide concentration it would be an acid.
the molecules are donated to water molecules. if a little of the acid remains after it is added to water, then it is a strong acid. if a lot remains, then it is a weak acid. same goes for bases.
By diluting it with water or neutralising it with a base or alkaline
When H2O is added to acid it begins to boil due to the strong reaction between the acid and the Base (the water). Don´t add H2O to acids add acid to water. Water is both an acid and a base, when it is reacting with acid it becomes base and reacts with base it becomes acid.
Acid and base when mixed in equal concentration neutralize each other.So if the water has both in equal concentration the water will not show the properties of the acid or the base.if any one i.e. acid or base is higher in concentration than the other the water will show its properties.
The added ethanol will not affect the pH whatsoever, due to the fact that ethanol cannot donate hydrogen ions or accept them. The added volume will, however, not affect the molar mass of the acid that you will report from the analyses.

Yes, heat of neutralization is directly proportional to the concentration of the acid. the more the concentration the more the heat emitted at the time of neutralization.
