question 87

Multiple Choice

The chemical acidity of a solution is measured in units of pH: $\mathrm { pH } = - \log \left[ \mathrm { H } ^ { + } \right]$ , where $\left[ \mathrm { H } ^ { + } \right]$ is the hydrogen ion concentration in the solution.If a sample of rain has a pH of 3.3, how many times higher is its $\left[ \mathrm { H } ^ { + } \right]$ than pure water's, which has a pH of 7?

• A) \(5.0 \times 10 ^ { 4 }\)
• B) \(2.0 \times 10 ^ { 4 }\)
• C) \(2.0 \times 10 ^ { 3 }\)
• D) \(5.0 \times 10 ^ { 3 }\)
• E)7
