The quality assurance lab just received a shipment of three solutions. The lab manager asks you to verify the stock solutions and label each bottle with the solution's hydrogen ion concentration, [H+]. You first use the pH meter to determine the pH of each solution. Calculate the hydrogen ion concentration of solution \#1, which has pH2.25. [H+]= Calculate the hydrogen ion concentration of solution \#2, which has pH7.25. [H+]= Calculate the hydrogen ion concentration of solution #3, which has pH10.75. [H+]=
