pH7 which is neutral and is normally the colour green
Alkali
No.Since,sodium nitrite(NaNO2)is a salt of strong base and weak acid,in water solution it will leave more amount of [OH-] ions.Hence, solution will be basic.Therefore,NaNO2 is base not an acid.
neutral
Tea is an acidic solution.
Adding an alkali to an acid solution would result in forming a salt. However, no acid solution can be neutral.
In acid-base reactions, neutralizing is when you add exactly enough chemical to bring the total solution pH to 7. If you have acid you put alkali in it; for alkali you add acid.
Alkali
The solution could be neutral, acidic or basic depending on the concentration or the volume of the acid or alkali used.

The pH of a solution.
neutral
Tea is an acidic solution.
For an acid, the solution remains colourless or unchanged. For an alkali, it would turn fuschia.
you create a neutral solution -------------------------------------------------------------------------------------------- Well it depends actually it doesn't always create a neutral solution. Here's the order: Strong Alkali + Strong Acid = Neutralisation (water + salt) Strong Alkali + Weak Acid = Weak Alkali Weak Alkali + Weak Acid = Neutralisation ( water + salt) Weak Alkali + Strong Acid = Weak Acid Strong Alkali + Strong Acid = Neutralisation (water + salt) Hope it helps! :)
Vinegar is a dilute solution of acetic acid.
An ammonia solution is alkaline.
Adding an alkali to an acid solution would result in forming a salt. However, no acid solution can be neutral.
