Ph of 7 examples
WebFor example, pure water is neutral with a pH of 7. A solution of common salt (sodium chloride) is also neutral, so it has a pH of 7 too. In science we often use the term aqueous … WebIn scientific notation, for example, if the concentration of this ion is 1x10^-10 mol/L, then the pH would be 10! Therefore, you can work backwards to see that if an acid had a concentration of 1x10^2 mol/L, then its pH would be -2! so basically negative pH indicates that the acid is very strong.
