An acid of the formula, HC6H5O, is a weak monoprotic acid. Its Ka is 1.1 x 10-10. A solution of this acid was prepared by adding 14.5 g of the acid in water to make 892 mL of solution. Calculate a) the equilibrium concentration of all the species, b) the pH for this solution and c) the percent dissociation. (Molar mass of HC6H5O = 94.11 g/mol)
An acid (HA) dissociates as follows: HA → H* + A minus Arrow should be interpreted as an equilibrium arrow. The pH of the 0.81 M solution of HA is 1.46. What is the K, of HA? Express your answer as a decimal, not an exponent. No unit, please. Your Answer: Answer
K, for formic acid, HCOOH, is 1.80x10-4. Ka for acetylsalicylic acid (aspirin), HC,H,04, is 3.00x10-4. Ка Ką for nitrous acid, HNO2, is 4.50x10-4. What is the formula for the weakest conjugate base?
A solution is prepared at 25°C that is initially 0.081M in methylamine CH3NH2 , a weak base with =Kb×4.410−4 , and 0.070M in methylammonium chloride CH3NH3Cl . Calculate the pH of the solution. Round your answer to 2 decimal places.
Acids & Bases: Understanding Connections Between Descriptions of Weak Acid Dissociation In an aqueous solution of a certain acid the acid is 0.054% dissociated and the pH is 4.49. Calculate the acid dissociation constant Ka of the acid. Round your answer to 2 significant digits.
In order to determine the Ka of HXO₂, a scientist prepared a HXO₂ solution with a pH=3. If the scientist determined the Ka to be 1.2 X 10⁻⁵, what was the molarity of the acid he started with? (If you use any assumptions, be sure to check that they are valid!) Round the final answer to the three decimal places.
can you help me on the second problem please
Determine the pH, pOH, [H+], and [OH-] for each of the following problems. We may assume each acid base listed will 100# dissociate.
A solution is prepared that is initially 0.38M in ethylamine (C₂H5NH₂), a weak base, and 0.12M in ethylammonium chloride (C₂H5NH₂C1). Complete the reaction table below, so that you could use it to calculate the pH of this solution. Use x to stand for the unknown change in [OH-]. You can leave out the M symbol for molarity. initial change final [C,HẠNH,] 0 0 [C,HẠNH] 0 0 [OH-] 0 010 X Ś
Which of the following statements about acids is true? o The conjugate base of a strong acid will significantly raise the pH of water O For a polyprotic acid, the first H* dissociation has the smallest K, O The conjugate base of a weak acid is a stronger base than H2O All of the other statements are false For a weak acid, the equilibrium [H3O]* = initial [HA]
you prepare a solution of 3.1 x 10-8M KOH and calculate the pH in the typical way for a strong base: calculate pOH (7.51), then pH = 6.49. When you place a pH meter in the solution you find that the pH is actually 7.11. What was wrong with your calculation? (Brief conceptual explanation is fine here – no calculations needed.)
