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 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.
What is the change in PH when an alkali is slowly added to an acidic solution?
The pH will increase as the alkali neutralizes the acid and shifts the solution towards being more basic. Initially, there will be a gradual increase in pH as the alkali reacts with the acid. Once all the acid is neutralized, the pH will stabilize at a value determined by the excess alkali.
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.
What happens to pH value when alkali is added to an acid?
The pH value increases when alkali is added to an acid because alkalis are basic in nature. The alkali neutralizes the acid, leading to a shift in the pH towards a more alkaline pH value.

What changes in PH occurs if an alkali is slowly added to an acidic solution?
As alkali is added to an acidic solution, the pH of the solution will increase. This is due to the neutralization reaction that occurs between the base (alkali) and the acid in the solution. The pH will gradually shift towards being more neutral as the reaction progresses.
How does the color change when a strong acid is added an alkali to neutralise?
When a strong acid is added to an alkali to neutralize it, the color change will often depend on the specific indicator used. For example, litmus paper turns red in acid and blue in alkali, while phenolphthalein changes from pink in alkali to colorless in acid. The color change is a result of the indicator's pH-sensitive properties signaling the shift in pH from basic to neutral as the acid and alkali react.
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.
What happens when drops of pH is added to an alkali?
When drops of a strong acid are added to an alkali, the pH will decrease due to the acidic nature of the acid. This will result in neutralization of the alkali as the acid and base will react to form a salt and water. The final pH will depend on the amount of acid added and the strength of the base.
How could you titrate an acid and alkali without the use of an indicator?
You can titrate an acid and alkali without an indicator using a pH meter. As the acid and alkali react, the pH of the solution changes. The endpoint of the titration is reached when the pH is neutral, indicating that all the acid has reacted with the alkali.
How will the pH change when an alkali is added to an acid?
idk, why're you asking me? you should've listened more in your chemistry class tut tut
Does water change the pH level of vinegar?
Yes, water can dilute vinegar and change its pH level slightly. Adding water to vinegar will decrease its acidity, thus raising the pH level. However, the change may be minimal depending on the amount of water added.
