Calculate pH and pOH for strong acids and bases

Paper 1, Paper 2 5 marks Difficulty 4

pH from hydrogen ion concentration power

A strong acid in a Melbourne classroom experiment has \([H^+]=1\times10^{-5}\,\text{mol L}^{-1}\). Calculate pH. Read the diagram first, then connect the value to the chemical meaning. Enter the answer and choose the interpretation that matches the chemistry.

Worked practice: chemistry evidence and answer

Use the chemical evidence first, then enter the result and interpretation that match it.
