Diagnostic Misconceptions - Water's Neutrality

Chemistry: AQA A Level, topic 2.5.12

Test yourself on Diagnostic Misconceptions - Water's Neutrality

  • Where do the hydrogen ions come from that allows pure water to have a pH value?

  • What is the pH of pure water at 40°C if Kw=2.916×10−14K_w=2.916\times10^{-14} mol2dm-6?

  • How do we calculate the hydrogen ion concentration of water given KwK_w?
