Calculate the hydroxide ion concentration
WebThe concentration of hydroxide ion in a solution of a base in water is greater than 1.0 × 10 − 7 M at 25 °C. The concentration of H 3 O + in a solution can be expressed as the pH of the solution; pH = − logH 3O +. The concentration of OH − can be expressed as the pOH of the solution: pOH = − log[OH −]. In pure water, pH = 7.00 and ...

WebExpert Answer. Solution is:- Chemical reaction is Ca (OH)2 Ca 2+ + OH- x x 2x …. This lab has you measure the hydroxide ion concentration and then calculate the calcium ion concentration present in the saturated solution of Ca (OH)2. If hydroxide ion concentration is 0.079 M, what is the calcium ion concentration, also in molarity? WebTo calculate the pOH of a solution you need to know the concentration of the hydroxide ion in moles per liter (molarity). The pOH is then calculated using the expression: pOH = - log [OH-] Example: 5 M? What is the pOH of a solution that has a hydroxide ion concentration of 4 x 10-pOH = - log [4 x 10-5] = - ( - 4) = 4. Calculating the Hydroxide ...
