### Possible Answer

Calculate concentration of hydroxide ion with given pH? Ist step, calculate pOH value by using formula pH + pOH = 14 2nd step, pOH = -log[OH], ... You will need Kw to determine the concentration of hydrogen ions and You will need the formula pH = Calculate concentration of hydroxide ion with ... - read more

To find the hydronium ion concentration from pH, set base 10 to the negative power of the pH. Here that corresponds to 10 to the power of -8.75The answer is 0.000000002 or 2x10^-9Although this response is correct in saying that concentration and pH are based on sets of base 10; however, it is ... - read more
