Adding NaOH will increase the pH of water, because NaOH is a base.
At 25°C:
pH < 7 is an acidic solution
pH = 7 is a neutral solution
pH > 7 is a basic solution

∙ 11y agowhen sodium is added to water ,sodium hydroxide is formed....Water can undergo a reaction called autoprotolysis, whereby one water molecule donates a proton (a hydrogen ion) to another, resulting in the formation of a hydroxide ion (OH-) and a hydronium ion (H3O+). This reaction can also be reversed, since hydroxide ions accept a hydrogen atom from hydronium ions to form a molecule of water. In pure water this two-way reaction is in equilibrium so that the concentration of hydroxide and hydronium ions in the water is equal. The negative log of the hydrogen ion concentration is called the pH; pure water has a pH of 7. The hydroxide ions from dissolved sodium hydroxide perturb this balance; as the additional hydroxides accept protons from hydronium ions, they decrease the hydrogen ion concentration, thereby increasing the pH.

Will NH3 increase decrease or no change in the pH when added to water?
The pH deccrease.
What substance forms a solution in water with a PH of 7?
Nothing because water is the only substance which has a PH of 7. Anything added to the water would change the PH unless you added pure water to it.
Describe a solution that contains a buffer?
Acetic acid is added to the solution, but the pH of the solution does not change. Sodium hydroxide, a base, is added to the solution, but the pH of the solution does not change.
When a strong base is added to water does the pH drop significantly?
The pH increase significantly.
What will happen to the hydronium ion concentration and pH of water if hydronium acid is added?
Hydrogen ions will form and the pH of the water will increase.
Does the pH of ethanol change if water is added?
It should change
Will NH3 increase decrease or no change in the pH when added to water?
The pH deccrease.
Does water change the pH level of vinegar?
no. water just dilutes the acid but the PH will not change unless an acid or alkali is added
What substance forms a solution in water with a PH of 7?
Nothing because water is the only substance which has a PH of 7. Anything added to the water would change the PH unless you added pure water to it.
Why did the water pH change?
The water pH will change when substances are added to water. If the pH is more than 7 it makes the water basic and if it is less than 7 the water is acidic.
What is the pH of water when ATP is added?
Not much change, ATP is neutral
Will NaOH increase decrease or no change in pH when added to water?
increase
What is the pH of Na2HPO4?
For example, to obtain a solution with the pH=7,00 mix: 756 mL 0,1 M solution of Na2HPO4 with 244 mL of 0,1 M HCl solution.
Will H2C2O4 increase decrease or no change in the pH when added to water?
the pH will decrease slightly as oxalic acid is a weak acid.
Why did PH change during the light experiment?
Because the Photosynthesis added carbon dioxide to the water
When KOH is added to water what does the pH of the water solution do?
The pH of water increase.
Will the pH change when an alkali is added to an acid?
Yes. The pH will increase.
