Do buffers react to acids and bases to keep pH in a?
Buffers are used to maintain the pH constant.
Do acids or base react with an indicator?
They both react, but and acid will create a low pH (1,2,3), and the color will turn red or orange. A base will have a high pH (11,12,13) and the color will be blue or green. edit: yes they do react. if it is an acid it has a pH of 1-6, 7 is neutral and a pH of 8-13 is a base. Presence of acids and bases can lead to protonation / deprotonation of the indicator molecule, which changes its colour
What is the imfortance of pH value of a substance?
The pH of a person's blood can tell a lot about their health. Knowing the pH of chemicals can tell how they will react to other chemicals, which can prevent accidents.
Does sodium carbonate react with phenolphthalein indicator?
no, only liquids w/ a ph below 7.0
What is the pH of alchohol?
I don't know the exact answer but take it like this... Carboxilic acids are around 500 times stronger than phenol and have a pH of ~ 3-4, and they will react with any base. Phenol is 1000 times stronger than alcohols and has a pH around 5.5 and will not react with carbonates but will with group 1 metals and group 1 metal hydroxides. On that bases I would assume alcohols would have a pH around 6.4, I do know they don't react with hydroxides or carbonates but will react with group 1 metals. However it does depend on the alcohol most alcohols will not even react with lithium (ethanol is the only one), as the alcohols get longer the less reactive they become, very long chain alcohols may only react with caesium or not at all.
When an acid and an alkali react what is the pH?
If they react until neutral then the pH will be 7. However, if there is an excess of acid the pH will be <7 and vice versa.
Why pH paper become reddish?
Components of pH paper react with acids or bases.

What is the pH level in Tums?
Tums react with acids from the stomach.

If a solution has a pH of 5 what would it react with to form a salt?
base

Could the change in the pH paper itself be a reaction Support your answer?
The substances contained in the pH paper react with the substance to be tested; and this is a chemical reaction.
Why doesn't turps react with pH indicators?
most pH indicators are polar, whereas turps is non-polar so it doesnt mix well
How is soil pH affected by water content?
when water content is high it react with CO2 produced as a result of respiration and produce carbonic acid which lowers pH.
