linked to their tax proposals. During this research, she requires a solution with a pH OF 12. What mass of the strong bass,Ba(OH)2,must she dissolve in 1.0L of water in order to obtain such a solution?

pH: ((from potential of Hydrogen) the logarithm of the reciprocal of hydrogen-ion concentration in gram atoms per liter; provides a measure on a scale from 0 to 14 of the acidity or alkalinity of a solution (where 7 is neutral and greater than 7 is more basic and less than 7 is more acidic).
The formula for pH is simply:
pH = - log (H+ ions)
Balance the equation - of putting Ba(OH)2 into H2O - and reverse the logarithmic function to determine how much ionic hydrogen is required. That will tell you how much of the Barium Hydroxide compound is required ... and hence the mass necessary to achieve the result.
