What is the pH of an aqueous solution of 2.20 \times 10^{-2} M potassium hydroxide? In direct contrast with HCl vs. HBr, HClO is a stronger acid than HBrO, because Cl is more electronegative, which dominates over the size difference between Cl and Br due to the presence of the oxygen. What is the pH of 0.25M aqueous solution of KBrO? What is the pH of 0.25M aqueous solution of KBrO? Calculate the pH and fractional dissociation of 0.83M of the weak base methylamine assuming that its Ka = 2.27 x 10^-11. Given that Kb for CH_3NH_2 is 5.0 10-4 at 25^o C, what is the value of Ka for CH3NH3 at 25^o C? a. 6.67. c. 3.77. d. 6.46. e. 7.33. A:An acid can be defined as the substance that can donate hydrogen ion. Calculate the pH of a 1.6M solution of hydrocyanic acid. What is the pH of a 0.530 M solution of HClO? R The compound is generated in warm-blooded vertebrate organisms especially by eosinophils, which produce it by the action of eosinophil peroxidase, an enzyme which preferentially uses bromide. What is the pH of an aqueous solution composed of 0.64 M NH4+ and 0.20 M NH3?
