- The solution becomes less acidic.
- Its pH increases and approaches 7.

If we dilute a basic solution:
- The solution becomes less basic.
- Its pH decreases and approaches 7

Comment: The dilution of an acidic solution increases its pH but it can not become greater than 7 because the added water is not basic.
Conversely the dilution of a basic solution decreases its pH, but it can not be less than 7 because the added water is not acidic]]> 2016-11-12 21:17:16 UTC https://padlet.com/mskmaye/jcinvestigationchemistry/wish/137155332 The effect of dilution on pH levels lynchj15 https://padlet.com/mskmaye/jcinvestigationchemistry/wish/137232101 Adding water to vinegar would cause the pH to increase because vinegar is an acidic substance.

Diluting an alkali by adding more water decreases the pH of the solution towards 7 making it less alkaline.

Since a pH value is an expression of the concentration of these ions, changing these concentrations by introducing more solvent causes the pH value to change.

The pH scale covers a range between 0 and 14 pH. A pH of exactly 7 is neutral. pH values greater than 7 are basic, while pH values less than 7 are acidic. The pH scale is logarithmic with a base of 10, meaning each integer pH value is 10 times more acidic or basic than the one preceding or succeeding it respectively. For dilution to decrease the acidity or basicity of a solution, the solvent being used must be less acidic or basic than this solution.

Alternatively, an acidic diluent may be used to dilute a basic solution, or vice versa, in a neutralization reaction. Because of the logarithmic nature of the pH scale, diluting a strong acid or base even slightly causes its respective pH to rise or drop considerably. Weak acids and bases with pH values close to 7 are correspondingly not as affected by dilution.

The term "pH" stands for "potential hydrogen" -- the more free-floating hydrogen ions in a solution, the more acidic the solution is. Vinegar's pH will always remain at a number lower than neutral, no matter how dilute it is, because vinegar is an acid.
