What effect will decreasing the H plus of a solution have on pH?

Decreasing the concentration of H+ ions will raise the pH of the solution because pH is a measure of the hydrogen ion concentration. As H+ ions decrease, the solution becomes more basic and the pH value increases.


What causes the pH of a solution of a solution to increase?

Adding a base will make the pH go up (increasing of OH- ions concentration).


What is the name of the ion in the ammonia solution that causes the pH of 10?

The ion that causes the pH of 10 in ammonia solution is the hydroxide ion (OH-). Ammonia (NH3) acts as a weak base and reacts with water to produce hydroxide ions, which increase the pH of the solution.


What is a pH indicators?

A pH indicator is a halochromic chemical compound that is added in small amounts to a solution so that the pH (acidity or alkalinity) of the solution can be determined easily. Normally, the indicator causes the colour of the solution to change depending on the pH.


Does baking soda raise or lower pH you?

Baking soda, also known as sodium bicarbonate, raises pH levels when added to a solution. It acts as a buffer and can neutralize acidic substances, thereby increasing the overall pH.


What would be the effect of using sodium hydroxide to raise the pH after addition of hcl?

Adding sodium hydroxide to a solution after the addition of hydrochloric acid will neutralize the acid and increase the pH of the solution. Sodium hydroxide is a strong base and will react with the hydrochloric acid to form water and salt, raising the pH of the solution towards neutral.


What causes low pH levels in a solution?

Low pH levels in a solution are caused by an increase in the concentration of hydrogen ions (H) in the solution. This increase in hydrogen ions makes the solution more acidic, resulting in a lower pH level.
