What is molarity?

Back

Molarity is a measure of the concentration of a solute in a solution, expressed as moles of solute per liter of solution (mol/L).

What is an indicator in chemistry?

Back

An indicator is a substance that changes color in response to a change in pH, used to identify acids and bases.

Front

What is a standard solution?

Back

A standard solution is a solution of known concentration used in titrations to determine the concentration of an unknown solution.

Front

What is a buffer solution?

Back

A buffer solution is a solution that resists changes in pH when small amounts of acid or base are added.

What is the chemical formula for carbonic acid?

Back

H2CO3.

Front

What is the chemical formula for nitrous acid?

Back

HNO2.

Front

How do you calculate molarity?

Back

Molarity (M) = moles of solute / liters of solution.

Front

What is the role of titration in chemistry?

Back

Titration is a technique used to determine the concentration of an unknown solution by reacting it with a standard solution.

Front

What is the significance of pH in solutions?

Back

pH measures the acidity or basicity of a solution, with lower values indicating acidity and higher values indicating basicity.

Front

What is the difference between strong and weak acids?

Back

Strong acids completely dissociate in water, while weak acids partially dissociate.
