Related Rate Problem....HeLp! 1. The problem statement, all variables and given/known data The ph of a solution is 3, ph changes at a rate of 0.01 at time t and the concentration of H3O is 10^-ph. At what rate is concentration decreasing at time t. 2. Relevant equations 3. The attempt at a solution I need someone to walk me through this if possible..I've never done a related rate question (or if I did I don't remember).
