adding something acidic
Yes, chlorine can lower the pH of wastewater because when chlorine is added, it can react with water to form hypochlorous acid, which is acidic. This can cause a decrease in the pH of the water.
A solution with a pH lower than that of distilled water would be acidic. This could be achieved by adding an acid such as hydrochloric acid or sulfuric acid to water. Acidic solutions have a pH below 7, with the lower the pH, the more acidic the solution will be.
Adding calcium hydroxide to water would raise the pH of the solution. Calcium hydroxide is a strong base and will dissociate in water to increase the concentration of hydroxide ions, leading to an increase in pH.
To lower the pH of 100 ml of water to a pH of 5.5, it would take only around a drop of lemon juice. It is estimated that in a gallon aquarium, two drops of lemon juice can lower the pH by .5.
A solution with a substance of 8.5 would be basic not acidic. NaOH would most likely cause this pH as it is a base whereas the reaction between HCl and water would cause a very stong acid.
Adding more hydrogen would cause more acidity thus a lower pH value.
No you add acid to lower the pH
Dissolving CO2 in distilled water would create carbonic acid, which would slightly lower the pH of the water. If added to a buffer solution, which resists pH changes, the pH may increase slightly due to the formation of carbonic acid, but the buffer would work to maintain the target pH by absorbing or releasing protons.
A solution with a pH lower than that of distilled water is considered acidic.
No, adding water to sodium hydroxide will not lower the pH. Sodium hydroxide is a strong base, and when dissolved in water, it dissociates to produce hydroxide ions, which make the solution more basic. To lower the pH of a sodium hydroxide solution, you would need to add an acid to neutralize the base.
Ammonia, which is basic, would raise pH. Vinegar, coffee and lemon juice are all acidic and would cause pH to be lower.
No it cannot. Sodium bicarb has a ph of 8.4. To lower ph you would need to use a dry acid (sodium bisulphate) or muriatic acid. City water is normally treated and has a ph of 7.5 but it would take a large amount of fresh water to lower the ph of a pool.
