pH strips
Acid can be detected using litmus paper which turns red when exposed to acids, while alkali turns it blue. Electronic pH meters can also be used to measure the acidity or alkalinity of a solution.
A green liquid called phenolphthalein is commonly used to determine if a chemical is an acid or alkali. Typically, it turns pink in the presence of a base (alkali) and remains colorless in the presence of an acid.
Cream is slightly acidic due to the presence of lactic acid from fermentation. An alkali is a base, which is the opposite of an acid on the pH scale. When cream is mixed with an alkali, the pH may shift towards neutral depending on the specific alkali used and the overall ratio of the mixture.
To neutralize an alkali, you can add an acid to it. The acid will balance out the pH level by reacting with the alkali. Common acids used for neutralization include hydrochloric acid, sulfuric acid, and acetic acid.
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.

What are the names of plants that can be used as indicator of acid and alkali
To neutralize an alkali, you can add an acid to it. The acid will balance out the pH level by reacting with the alkali. Common acids used for neutralization include hydrochloric acid, sulfuric acid, and acetic acid.
Nitric acid is used in Gmelin's test to detect the presence of manganese in a sample. The reaction involves the formation of a green precipitate of manganese dioxide, which indicates the presence of manganese.

Acid.
xanthoproteic test is used to detect the presence of aromatic amino acid in this nitration of an benzee ring with nitric acid takes place.
Ehrlich's reagent, used to detect the presence of indole compounds, typically consists of p-dimethylaminobenzaldehyde dissolved in a strong acid, such as hydrochloric acid or sulfuric acid.
Iodine does not directly react with acids. However, when iodine is added to an acid solution, it can form hypoiodous acid (HOI) which is a weak acid. This reaction can be used in analytical chemistry to detect the presence of iodine.
