What is a strong acid?

Back

A strong acid is an acid that completely ionizes in solution, releasing all of its hydrogen ions (H+). Examples include hydrochloric acid (HCl) and sulfuric acid (H2SO4).

Front

What is a strong base?

Back

A strong base is a base that completely dissociates in solution, releasing hydroxide ions (OH-). Examples include sodium hydroxide (NaOH) and potassium hydroxide (KOH).

What is the solubility rule for nitrates?

Back

All nitrates (NO3-) are soluble in water.

Front

What is the solubility rule for alkali metal salts?

Back

All alkali metal salts (Li+, Na+, K+, etc.) are soluble in water.

Front

What is a titration?

Back

A titration is a laboratory method used to determine the concentration of an unknown solution by adding a known volume of a solution of known concentration until the reaction reaches completion.

Front

What is the formula to calculate molarity (M)?

Back

Molarity (M) is calculated using the formula: M = moles of solute / liters of solution.

Front

How many liters of solution are needed to make a 1 M solution with 6 moles of NaOH?

Back

6 liters are needed to make a 1 M solution with 6 moles of NaOH.

Front

What is the pH of a strong acid solution?

Back

The pH of a strong acid solution is typically less than 7, with lower values indicating higher acidity.

Front

What is the pH of a strong base solution?

Back

The pH of a strong base solution is typically greater than 7, with higher values indicating higher basicity.
