Edexcel IAL Chemistry A2 14.7 pH of a strong acid
Treat a strong monoprotic acid as fully dissociated, then use moles and total volume where mixing or dilution changes the hydrogen ion concentration before finding pH.
How this is tested
- Calculate pH directly as -log10[H+] for fully dissociated strong monoprotic acids.
- Use acid-base moles and total volume before finding pH for a mixture with excess acid.
- Predict the pH decrease when strong-acid concentration is increased or diluted.
