Homework Statement
Shells of mussels are mainly of calcium carbonate. IUsually the shell is stable and its content is in equilibrium with the surrounding. Mussels need to build up or reduce their shell, however, for additional protection or during growth. They achieve this by changing the pH-value of the seawater in their surrounding.
Assume that the concentration of Ca2+ ions in seawater and in the vicinity of a mussel bank is 0.01 M and that the total concentration of "inorganic carbon" in seawater is 0.0023 M.
Calculate the pH(correct to 2 decimals) of the water in the vicinity of mussels so that their shell remains stable
Homework Equations
pH = -log[H]
Not sure if this is relevant: pH = -log[Activity of Hydrogen]
The Attempt at a Solution
Not sure on what to do. I know that that to find pH, we need to find the hydrogen concentration. I am thinking that activity of hydrogen might be involved but not sure. Any help is appreciated. Thanks
