pH Calculator
This tool calculates the pH of either an acid or base solution when given a certain set of parameters. Users can select to input either the compound's concentration, or the mass of the solid and the total volume of the solution. Ka values can either be inputted manually or auto-filled by selecting an acid or base from the table, and any of the values within the calculator can be determined when provided with the rest of the parameters.
