Solubility and Acids and Bases

Front

What is solubility?

Back

Solubility is the ability of a substance (solute) to dissolve in a solvent, typically measured in grams of solute per 100 grams of solvent.

Front

What is the pH scale?

Back

The pH scale measures the concentration of hydrogen ions in a solution, indicating how acidic or basic the solution is, ranging from 0 (acidic) to 14 (basic).

Front

What is a saturated solution?

Back

A saturated solution is one in which the maximum amount of solute has been dissolved in a solvent at a given temperature.

Front

What is a supersaturated solution?

Back

A supersaturated solution contains more solute than can normally dissolve at a given temperature, often achieved by heating the solution and then cooling it.

Front

What is a neutralization reaction?

Back

A neutralization reaction is a chemical reaction between an acid and a base that produces water and a salt.

Front

What are bases?

Back

Bases are substances that can accept hydrogen ions (H+) or donate electron pairs in reactions, often feeling slippery and having a bitter taste.

Front

Why are bases useful as cleaning products?

Back

Bases are useful as cleaning products because they dissolve fats and oils, making it easier to remove dirt from surfaces.

Front

What is the formula for calculating solubility?

Back

Solubility (g/100g of solvent) = (mass of solute / mass of solvent) x 100.

Front

What happens to the pH of a solution when an acid is added?

Back

When an acid is added to a solution, the pH decreases, indicating an increase in hydrogen ion concentration.

Front

What is the difference between strong and weak acids?

Back

Strong acids completely dissociate in water, releasing all their hydrogen ions, while weak acids only partially dissociate.
