Strong acids produce _____ than weak acids do.

• fewer hydroxide ions

• fewer hydrogen ions

• more hydroxide ions

• more hydrogen ions

Which is Not true concerning pH scales.

• In a solution, the lower the pH value, the fewer hydronium ions present.

• The pH scale gauges how acidic a substance is.

• The pH value is a unitless number between 0 and 14

• The pH value is determined by the amount of hydronium ions that are produced in a solution.
