✓ Answer: B 7
The pH value of pure water at 25°C is 7. This means that the concentration of hydrogen ions and hydroxide ions is equal in pure water, and there is no acidic or basic character. At 25°C, the concentration of both hydrogen ions and hydroxide ions in pure water is 1×10^-7 mol/L, resulting in a neutral pH of 7.
