Normality, molarity, molality, and molarity are different units of concentration used in chemistry.

• Normality is a measure of the concentration of a solute in a solution based on its equivalent weight.

• Molarity is a measure of the concentration of a solute in a solution based on the number of moles of solute per liter of solution.

• Molality is a measure of the concentration of a solute in a solution based on the number of ...read more

H2SO4 has a higher concentration than HCl.

• Concentration is determined by the number of moles of solute per unit volume of solution.

• H2SO4 has a higher molar mass than HCl, so the same volume of H2SO4 will contain more moles of solute.

• Therefore, H2SO4 has a higher concentration than HCl.

• For example, if we have 100 mL of 1 M H2SO4 and 100 mL of 1 M HCl, the H2SO4 solution will contain more moles of solute.

Acetic acid is a weak acid commonly found in vinegar.

• Acetic acid is the main component of vinegar.

• It has a chemical formula of CH3COOH.

• It is a weak acid because it only partially dissociates in water.

• Other examples of weak acids include citric acid, formic acid, and carbonic acid.
