First of all it is NOT 'Ph'. It is correctly symbolized as 'pH'.

The 'p' is the symbol for the negative logarithm to the base ten'.

'H' is the hydrogen ion concentration.

For Acid the pH range is 1 - 6 ( The lower the number , the stronger the acid).

For Water the pH is 7 (only).

For Alkalis the pH range is 8 - 14 ( The higher the number , the stronger the alkali).

NB. pH only ranges from 1 - 14. It does not range outside these values.

What is the pH for an acid?

pH stands for " power of hydrogen" when the water breaks (H2O) you get H+ ( also H3O+) and OH- so pH is the power of H+ You can also calculate pH with this formula : pH = - log10 x [H3O+] [H3O+] - this is the number of thes kations pH rate is from 0 to 14 where 7 is neutral (water), <7 is acid and >7 is base


How can the pH be lowered in water treatment processes?

The pH in water treatment processes can be lowered by adding acidic substances, such as sulfuric acid or hydrochloric acid, to the water. These substances help neutralize alkaline compounds and reduce the pH level to the desired range.


What is pH of an acid?

The range of an acid is to 1 to 6........


Is acid used in salt pools?

Yes, acid controls the pH of the pool water. The higher the pH the less effective the chlorine is and the more prone it is to scaling. The ideal pH range is 7.2-7.6.


What is the pH range of and acid?

The pH range of an acid is typically below 7 on the pH scale. Strong acids have a pH closer to 0, while weak acids have a pH closer to 7.


What happens to pH of water when hydrochloric acid is added to water?

The pH of water decreases when hydrochloric acid is added to it because hydrochloric acid is a strong acid that donates protons in water, increasing the concentration of hydrogen ions and lowering the pH of the solution.


When hydrochloric acid a strong acid is added to water the pH oh water is?

The pH of water will decrease when hydrochloric acid, a strong acid, is added to it. This is because the strong acid will increase the concentration of hydrogen ions in the water, leading to a lower pH.


What range of pH values corresponds to acid solution?

The possible range of pH for an acid would be anything lower than 7 and above zero.


What is the range of pH in acid and how this is linked to the concentration of acid?

in pH acids range from 0-6.as the highest value is 6 and if the concentration of an acid is 6 it is concentrated as this value drops the concentration drops


How does the presence of an acid in a water solution affect of the pH of the solution?

The presence of an acid lowers the pH of the solution in water.


How does the presence of an acid in water affect the pH of a solution?

The presence of an acid reduces the pH.


How much acid to add to water to pH9?

To raise the pH of water from neutral (pH 7) to pH 9, you would need to add an acid in small amounts while monitoring the pH. It is recommended to use a pH meter or test strips to accurately measure the pH and slowly add the acid until reaching pH 9. The exact amount of acid needed would depend on the volume of water and the strength of the acid being used.
