How does an acid affect pH and H plus concentration when added to water?

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

∙ 13y agoA 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.

∙ 7y agoThe 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.

Wiki User
∙ 15y agoNothing. Since water is neutral, the pH remains the same.
Wiki User
∙ 15y agoThe pH number will go to 7, same thing that will happen if an acid is added to an base.
Wiki User
∙ 10y agoThe presence of an acid lowers the pH of the solution in water.
Wiki User
∙ 12y agoPure 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.

What will happen to hydrogen ion concentration and the pH of water if hydrochloric acid added to water?
When an acid (any) is added the H+ concentration goes up, and the pH goes down.
What ion increases in concentration when a strong acid is added to water?
H3O+ (or just H+)
When NaH is added to water the hydroxide concentration increases what can you include about NaOH?
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 you add water to acid what forms?
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 solid acid is dissolved in 100 mL of deionized water followed by 10 mL ethanol How does this added volume affect?
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.

What ion increases in concentration when a strong acid is added to water?

What will happen to the hydronium ion concentration and pH of water if hydronium acid is added?
Hydrogen ions will form and the pH of the water will increase.
What is an arrhensius acid?
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-
What will be form in combining acetic acid and water what kind of solution is it?
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.
When NaH is added to water the hydroxide concentration increases what can you include about NaOH?
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.
What happens to most of the molecules of a strong acid when the acid is mixed with water?
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.
How can you change the concentration of acid?
By diluting it with water or neutralising it with a base or alkaline

What are the main properties of acid base water?
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.

Does changing the concentration of an acid affect the temperature at neutralisation?
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.
