Please answer these questions on your Page 9 We dissolve 2.66 g of an unknown acid, HA, in enough water to produce 25.0 mL of solution. The pH of this solution is 1.11. We titrate this solution with a 0.166 M NaOH solution and we need 22.2 mL of this NaOH solution to reach the equivalence point. The temperature is 25.0°C throughout. (a) What is the molar mass of HA? (b) What is the dissociation constant, K₁, of A-(aq)? (c) What was the pH of the solution after the addition the first 15.0 mL of the NaOH solution?

Calculate the pH values of the following solutions. All solutions are prepared in water at 25 oC unless noted otherwise. Kw = 1.0 × 10−14 = [H3O+]×[OH−] at 25 oC. The neutral pH of pure water is 7.00 at 25 °C. If the Kw is 1.47×10−14 at 40 °C, calculate the neutral pH of pure water at 40 °C. A neutral pH means the pH of a solution when [H3O+] = [OH−]

Question 34 of 35 A student was titrating a solution of HC H,O, with a Sr(OH), solution. Determine the pH at a particular point in the titration. To do this, construct an ICE table to the concentration of hydroxide in solution and then use this information to determine the pH (Part 2). Complete Parts 1-2 before submitting your answer. NEXT 40.0 mL of a 0.200 M HC H,O, solution was titrated with 100 mL of 0.100 M Sr(OH), (a strong base). Fill in the ICE table with the appropriate value for each involved species to determine the moles of reactant and product after the reaction of the acid and base. You can ignore the amount of water in the reaction.

pH is a logarithmic scale used to indicate the hydrogen lon concentration, [H], of a solution: pH = -log[H] Due to the autoionization of water, in any aqueous solution the hydrogen lon concentration and the hydroxide ion concentration, (OH], are related to each other by the K of water K.-HOH -1.00 x 10-¹4 where 1.00 x 104 is the value at approximately 297 K Based on this relation, the pH and pOH are also related to each other as 14.00 pH + POH The temperature for each solution is camned out at approximately 297 K Part A ▸ 0.55 g of hydrogen chloride (HCT) is dissolved in water to make 55L of solution.
