Add an alkali substance to it, such as chalk, if it is an acid it will "fizz" and release carbon dioxide. You could also test with Litmus Paper or Universal indicator.
You can tell if a fruit has acid in it if that fruit has a sour taste to it.Examples:LemonsGrapesLimesOrangesApples
We could tell the solution was an acid by reading the pH scale.
The litmus test can help determine if sulfurous acid is an acid or a base. If sulfurous acid turns blue litmus paper red, it indicates that it is an acid. This test does not provide direct information about the stability of sulfurous acid.
Using an indicator.
Provided it is yellow, put it in nitric acid. If not huing the acid, that is pure gold in contact with the acid
you get a scale like this
To check if it is a carbonate or not
ph
An acid has a pH level below 7 whereas a base has a pH level above 7.
For an acid, the solution remains colourless or unchanged. For an alkali, it would turn fuschia.
Water has the chemical formula H2O. Acetic acid has the formula CH3COOH.
acid rain is made acidic by pollution in the air. acid rain erodes stone buildings , statues and kills plants and fish .
