    the effects of an incorrect pH level. pH measures the concentration of hydronium ions and can be modeled by the function p(t) = −log10t. The variable t represents the amount of hydronium ions; p(t) gives the resulting pH level. Water at 25 degrees Celsius has a pH of 7. Anything that has a pH less than 7 is called acidic‚ a pH above 7 is basic‚ or alkaline. Seawater has a pH just more than 8‚ whereas lemonade has a pH of approximately 3. 1) Create a graph of the pH function either by hand or using
