Is water needed to see if it is an acid or an alkali?

Yes, because the pH is measured in a solution.


What happens to the pH when an alkali is added to a acid?

When an alkali is added to an acid, the pH increases as the acid is neutralized by the base. This reaction forms water and a salt. The pH ultimately depends on the strength of the acid and the alkali.


How do you know pH 11 is acid?

pH 11 is an alkali not an acid


When an acid is neutralised by an alkali the pH decreases.?

No, the pH increases.


Will the pH change when an alkali is added to an acid?

Yes, the pH will change when an alkali is added to an acid. The addition of an alkali to an acid will result in the neutralization reaction, forming water and salt. This reaction will change the pH towards being more neutral.


What does adding alkali to acid do to pH?

The solution become more and more alkaline and the pH increase.


What is the change in PH when an alkali is slowly added to an acidic solution?

The actual answer depends on the strength of the acid / alkali used. However the pH will change from around 1-6 to 8-14 depending on the strength of the acid / base. pH ~1 for strong acid pH ~6 for weak acid pH ~8 for strong base pH ~14 for strong base


What happens to pH value when alkali is added to an acid?

If you are asking about acid then the pH value will go from 7- to 7+.... If you are asking about the alkali the pH value will go from 7+ to 7-....


How can you describe the way the pH changes when a strong acid is added slowly to a strong alkali?

As a strong acid is added slowly to a strong alkali, the pH will gradually decrease due to the neutralization reaction. Initially, the pH will increase as the alkali is added, then start to decrease as the acid is added until it reaches a neutral pH of 7 when the acid and alkali are fully neutralized.


When an acid and an alkali react what is the pH?

When an acid and an alkali react, they neutralize each other, resulting in a solution with a pH close to 7, which is considered neutral. The pH will depend on the specific amounts and strengths of the acid and alkali used in the reaction.


Is Borax a acid or alkali?

Borax is an alkali, specifically a salt of boric acid. It has a basic pH value and can act as a buffer solution to help regulate pH levels in various applications.


What happens to the pH when acid is added to an alkali does it go up or down?

When acid is added to an alkali, the pH decreases or goes down. This is because the acid donates hydrogen ions (H+) to the alkali, neutralizing the alkaline properties and shifting the pH towards neutrality or acidity.
