Overview of Solutions and Concentration Terms

Flashcards cover key concepts related to solutions, concentration terms, and properties essential for exam preparation.

What is a solution?

A mixture of two or more non-reacting chemicals that are mixed homogeneously.

What is the maximum particle size of a solution visible to the naked eye?

Less than 1 nm.

What are binary, ternary, and quaternary solutions?

Binary solution has 2 components, ternary solution has 3 components, and quaternary solution has 4 components.

What is a dilute solution?

A solution that contains a less amount of solute in a large amount of solvent.

What is a concentrated solution?

A solution that contains a high amount of solute in a given amount of solvent.

What is the formula for calculating molarity (M)?

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

What does 'aqueous solution' mean?

A solution where water is the solvent.

What does 'alcoholic solution' mean?

A solution where alcohol is the solvent.

What is normality (N)?

Normality is defined as the number of gram-equivalents of solute present in 1 liter of solution.

How is molality (m) defined?

Molality is the number of moles of solute per kilogram of solvent.

What is the relationship between molarity (M) and molality (m)?

Molality (m) = 1000 x M / density of solution.

What is the definition of parts per million (ppm)?

It represents the number of parts of solute present in one million parts of solution.

What is the significance of n-factor in chemistry?

The n-factor is used to define the equivalent mass of a substance in a chemical reaction.

What is a mixing of solutions?

Mixing solutions involves combining the volumes and concentrations of different solutions.

What happens when two acids are mixed?

The normality of the mixture is the sum of the normalities of the individual acids multiplied by their volumes.

What indicates an acidic solution when mixing acids and bases?

If the total normality of acids exceeds that of bases, the mixture is acidic.

How is strength defined in the context of solutions?

Strength is defined as the mass of solute present in a given volume of solution.

What is the formula for calculating strength?

Strength = Wsolute / Vsolution.
