There are three types of substances acids, bases, and neutrals. The properties of an acid include they are sour, have a PH of less then 7, corrosive to skin, contains hydrogen, and reacts to litmus paper.
Acids turn litmus paper red. Bases turn litmus paper blue. If the paper turns orange, its an acid.
Recreation of an indicator using an acid and a base involves mixing a colorless or faintly colored acid-base indicator with an acid to make the solution acidic (and change color) and then adding a base to neutralize the acid and return the indicator to its original color. This process demonstrates the reversible nature of acid-base indicators and how they can be used to visually indicate the presence of acids or bases in a solution.
An indicator used to detect an acid or base is a substance that changes color in the presence of acids or bases. Examples of indicators include litmus paper, phenolphthalein, and universal indicator solution.
When acid is put on china rose indicator, the indicator will turn red in color. This color change indicates that the solution is acidic. China rose indicator contains anthocyanin pigments that change color based on the pH of the solution.
depends on the indicator used. in case of red litmus... changes to blue for basesand no change in acids blue litmus - changes to red in acids, no change in bases phenolpthelin - changes to pink in bases, no change in acid methyl orange - changes to red in acids and yellow golden in bases

The indicator of acid is baking soda.
for one never taste it but, you will need an acid-base indicator to identify it...you can thank me later

A pH indicator changes color depending on the acidity or basicity of the solution it is in. In an acid, the indicator will have one color and in a base, it will have a different color. By observing the color change in the pH indicator, one can determine whether the solution is acidic or basic.
Litmus is a pH indicator that can change color when in contact with acids or bases. Blackcurrant is a fruit that contains a mixture of organic acids such as citric acid and malic acid, making it slightly acidic.
Phenolphthalein is typically used as a base indicator as it changes color in the presence of bases. Bromthymol blue can be used as both an acid and a base indicator, with different color changes for each.
It is litmus, an extract from several different species of lichens, that is used as an indicator between acid and alkaline conditions.
Citric acid is generally colorless in universal indicator. It is a weak acid, so it does not exhibit a strong color change in the indicator solution.
