Define the following: Quantitative analysis 2 salt 3 Alum 4 Acidic salt?

1. Quantitative analysis: A method of analysis that determines the amount or concentration of a substance in a sample, typically using numerical data and measurements.

2. Salt: A compound formed when the hydrogen ions of an acid are replaced by metal ions or other positive ions. Common table salt is sodium chloride (NaCl).

3. Alum: A class of chemical compounds that are double salts, typically consisting of aluminum sulfate, potassium sulfate, and another sulfate. Alum is commonly used in water purification, as a mordant in dyeing, and in various other industrial processes.

4. Acidic salt: A salt that is formed by the partial neutralization of an acid, resulting in a compound that still retains acidic properties. Acidic salts can react with water to produce an acidic solution.

1. Quantitative analysis:
>A method of determining the amount or concentration of a particular substance in a sample.

2. Salt:
>A compound formed by the reaction of an acid with a base.

3. Alum:
>A type of salt that contains the sulfate ion (SO42-) and the aluminum ion (Al3+).

4. Acidic salt:
>A salt that contains a hydrogen ion (H+).
