WebThe inverse proportional relation between Ka and Kb means the stronger the acid or base, the weaker its conjugate partner.Figure 34.2 illustrates this relation for several conjugate acid-base pairs.. Figure 23.2. Relative strengths of several conjugate acid-base pairs are shown. Figure 23.3. This figure shows strengths of conjugate acid-base pairs relative to … WebTranscribed Image Text: On the weak acid/strong base titration curve, label A. the point where the pH corresponds to a solution of the weak acid (HA) in water; B. the point where the pH corresponds to a solution of the conjugate base (A¯) in water; C. the point where pH = pka. pH 7 mL of titrant с Answer Bank A B WebThe conjugate base of a very weak acid is stronger than the conjugate base of a strong acid. A strong acid is composed of a proton and an anion that have a very strong attraction for one another. A strong acid has a strong conjugate base. A weak base is composed of a cation and an anion with a very weak attraction between them. swiss life operations gmbh

Conjugate acid of a weak base

WebA weak monoprotic base has a K b = 2.94 × 10 −7. Calculate the K a for the conjugate acid of this base. Report your answer to THREE significant figures. You may (but are not required to) enter your answer in scientific notation; for example, if your answer is 2.44 × 10-2, you would enter 2.44E-2. The E must be uppercase. 1c. Weba. Strong acids produce solutions with a higher pH than weak acids. b. Strong acids are 100% ionized in water. c. Strong acids are very concentrated acids. d. All acids have H atoms bonded to electronegative oxygen atoms. e. The conjugate base of a strong acid is itself a strong base.
