Review acids as hydrogen ion producing substances in solution. Discuss the use of the pH measurement to indicate acid strength rather than using hydrogen ion concentration in moles/l in scientific notation. Show how the scientific notation can be converted to a simple number through the use of the log of the concentration. Indicate the pH as a number from 0 14 and indicate acid, neutral, and basic solutions. Define how as the pH increases from zero, the acid strength decreases by a factor of 10. Determine 7 as neutral. Determine if some common products are acids or bases by their pH
