Base turn red cabbage solution to blue-ish purple
Adding base will increase pH-level
It will turn a red color indercating that is has got acid in it
it turns greenish yellow if it is added to a base
it is a controll when a acid or a base is added it changes color
The acid and base will neutralize each other and the resulting solution will be more neutral. If the base being neutralized is strong, the resulting salt will be neutral. If the base is weak the resulting salt will be acidic. A solution of such a salt may be called a buffer.
sodium hydroxide, a base, is added to the solution, but the pH of the solution does not change.
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 acid is added to a buffer solution at pH 7, the pH of the buffer solution will decrease. However, due to the presence of a conjugate base in the buffer solution, the buffer will resist the change in pH and try to maintain its original pH value. This is because the conjugate base will react with the acid and prevent a significant decrease in pH.
a neutral
Increase
When small amounts of acid or base are added to a buffer solution, the buffer functions to keep the pH from changing.
Generally base is added to HCl, So base should be tested.
