- The formula for tartaric acid is preferably written as H2C4H4O6 rather than as C4H6O6. Explain why.arrow_forward5. The molarity of an aqueous solution of NaOH is 0.0022 M.(a) What is the concentration of H3O+ in this solution?(b) What is the pH of the solution?(c) What is the OH- concentration in the solution?arrow_forwardThe active ingredient of bleach such as Clorox is sodium hypochlorite (NaClO). Its conjugate acid, hypochlorous acid (HClO), has a Ka of 3.0 × 10–8. (a)The undiluted bleach contains roughly 1 M NaClO. Calculate the pH of 1 M NaClO solution. (b)Some applications require extremely diluted bleach solution, such as swimming pools. Suppose the solution in (a) is diluted by 10,000 -fold. Calculate the pH of the diluted solution, and demonstrate that you can still neglect the autoionization of water in your calculation. (c)Suppose the solution in (a) is diluted by 1million-fold, briefly explain how your approach will be different. Write the equation with [H3O+] as the unknown, but you do not need to solve it.arrow_forward
