Solutions Test Review

Front

What is the molarity (M) of a solution?

Back

Molarity (M) is a measure of the concentration of a solute in a solution, defined as the number of moles of solute per liter of solution.

Front

How do you calculate the number of moles from molarity and volume?

Back

Number of moles = Molarity (M) × Volume (L).

Front

What is the solubility of KBr at 80°C?

Back

The solubility of KBr at 80°C is 100g per 100mL of water.

Front

What does a pH of 6.4 indicate about a substance?

Back

A pH of 6.4 indicates that the substance is slightly acidic.

Front

What are the products of a neutralization reaction?

Back

The products of a neutralization reaction between an acid and a base are water and a salt.

Front

How do you convert mL to L?

Back

To convert mL to L, divide the volume in mL by 1000.

Front

What is the formula to find the number of moles in a solution?

Back

Number of moles = Molarity × Volume (in liters).

Front

What is the significance of a solution being 'neutral'?

Back

A neutral solution has a pH of 7, indicating equal concentrations of hydrogen ions (H+) and hydroxide ions (OH-).

Front

What is the relationship between pH and acidity?

Back

Lower pH values (below 7) indicate higher acidity, while higher pH values (above 7) indicate basicity.

Front

What is the definition of solubility?

Back

Solubility is the maximum amount of solute that can dissolve in a given amount of solvent at a specific temperature.
