Using an eye dropper, base was added from the graduated cylinder into the acid until the endpoint was identifed. At this point, 35.5 mL of base remained in the graduated cylinder. Calculate [sulfuric acid].If the pH of a solution is 5.6, what is the concentration of [OH-] in solution? Use the following answer format: 1x10-14 Use the correct number of significant figures.
- In chemistry, the pH of a solution is a measure of the acidity or alkalinity of a solution. Water has a pH of 7 and, in general, acids have a pH less than 7 and alkaline solutions have a pH greater than 7. Find the pHpH of a solution with a hydronium ion concentration of 7.7 x 10-5 moles/liter. Round your answer to two decimal places, if necessary.Give the name and identify each of the following as an acid or a base: Substance Name Acid or Base H2SO4 Ca(OH)2 Mg(OH)2 HCl (aq)Calculate the concentration of an aqueous solution of Ca(OH)2Ca(OH)2 that has a pHpH of 11.52. Express your answer using two significant figures.
