Document Summary
Disorders of acid/base balance ph = -log [h+] ph = -log [10^-7] ph = 7. 10^-6, the solution is more concentrated than 10^-7 ph = -log [10^-6] ph = 6. As you keep increasing the h+ concentration by a factor of 10, whatever the concentration is, the ph will be the exponent. If you increase the [h+] to 1, the ph would be 0. 1 m hcl ph would be 0. Normal ph scale is anywhere from 1-14, but can go beyond at both ends. Understanding that h+ concentration and oh- concentration have an inverse. If you increase further and have a 10 m hcl solution, ph = -1 relationship. As h+ concentration increases, ph does down. Water is made up of h2o and dissociates into h+ and oh- (10^-7 m concentration of each) Kw = [h+] [oh-] / [h2o] (water constant)
