Add an acid or a base to the solution to change the pH. Adding an acid will decrease the pH, while adding a base will increase the pH. The amount that the pH increases or decreases is dependent on the strength and concentration of the acid or base.
Some common acids include hydrochloric acid (HCl), nitric acid (HNO3), sulfuric acid (H2SO4), and acetic acid (CH3COOH).
Some common bases include sodium hydroxide (NaOH), potassium hydroxide (KOH), and ammonia (NH3), which when added to water is the same as ammonium hydroxide (NH4OH).
You can also add a buffer to the solution. This is not good for changing the pH a great deal of a solution that is already acidic/basic, but if you want to make a solution from water at a certain pH, the best way to do this is with a buffer. A buffered solution is also resistant to changes in the pH which is useful for carrying out reactions at a certain pH.
See the Related Questions links to the left for more information about how to prepare a buffer solution and how to calculate the pH of solution.

Which change shows a tenfold increase in concentration h ions?
pH 2 -> pH 1
What shows a tenfold increase in concentration of H plus ions?
A change in pH of 1 unit is equivalent to a 10 fold change in the concentration of H+ ions. So, a 10 fold increase in H+ ions will lower the pH by 1 pH unit.
If stomach acid has a PH of 1 and a person took a tums tablet which raised the PH to 3 how much was the increase in PH?
The increase in pH would be 2, as going from a pH of 1 to a pH of 3 represents a change of 2 pH units.

Will the pH change when an alkali is added to an acid?
Yes, the pH will change when an alkali is added to an acid. The addition of an alkali to an acid will result in the neutralization reaction, forming water and salt. This reaction will change the pH towards being more neutral.
Will NH3 increase decrease or no change in the pH when added to water?

How will soil pH change as you go further away from a lake?
The pH of soil will change as you move further away from a lake due to the increase of nutrients found in soil.
What colour does pH paper change to if sodium bicarbonate is added?
pH paper would change from red to yellow when sodium bicarbonate is added because sodium bicarbonate is a base and would increase the pH of the solution.
Which change shows a 10 fold increase?
Many changes show a 10 fold increase, but if you are talking about every day chemistry phenomena, then it would be pH. Every change of 1 pH unit represents a 10 fold change in the hydronium ion concentration.
What happens in a buffer when the level of H ions in the solutions increaSE?
there will be no change .because the buffer resist change in ph.
What happens in a buffer when the level of H ions in solutions increase?
there will be no change .because the buffer resist change in ph.
