Concept explainers
(a)
Interpretation:
Stronger acid in the given set of compounds has to be selected.
Concept introduction:
Acid - ionization constant
Acids ionize in water. Strong acids ionize completely whereas weak acids ionize to some limited extent.
The degree to which a weak acid ionizes depends on the concentration of the acid and the equilibrium constant for the ionization.
The ionization of a weak acid
The equilibrium expression for the above reaction is given below.
Where,
Smaller value of

- 6. Which of the following statements is true about the following acid/base reaction? F (aq) + HSO4 (aq) 5 HF (aq) + S0,² (aq) 2- a) F is an acid. b) HF is the conjugate acid of SO42. c) SO,² is the conjugate base of HSO4". d) F¯ is the conjugate base of HSO4". e) none of the abovearrow_forwardFluorosulfuric acid (HSO3F) is considered a superacid because it is stronger than sulfuric acid (H2SO4). The H2SO4 structure can be changed to HSO3F by simply replacing an -OH group with a F atom. With this in mind, explain why HSO3F is a stronger acid than H2SO4.arrow_forwardUsing pK, values given in Table 4.1, predict the position of equilibrium in this acid-base reaction and calculate its K H,PO, + CH,CH,OH=H,PO, + CH, CH, OH,+arrow_forward
- Choose the strongest acid from each group. (a) HClO, HBrO, HIO (b) HIO, HIO3, HIO4 (c) HIO, HBrO2, HBrO4arrow_forwardThe hydride ion is very basic and reacts readily with compounds having even weakly acidic protons to form H2. True or false?arrow_forwardFor each conjugate acid-base pair, identify the first species as an acid or a base and the second species as its conjugate acid or base. In addition, draw Lewis structures for each species, showing all valence electrons and any formal charge. (a) NH4+ NH3arrow_forward
- What is Ka for the conjugate acid of HONH₂ (Kb = 1.1 × 10⁻⁸)?arrow_forwardPhosphoric acid is a tri-acid. It is often associated to biological molecules (i.e. proteins, lipids) in the form of phosphate group. Its ionisation state depends on the pH of the solution and of its pKa values. Data: pka₁ = 2.1; pKa₂ = 7.2 ; pka3 = 12.4 1- What are the forms present at physiological pH (7.4) ? 2- Indicate which form is the most prominent.arrow_forwardwhich acid of each pair would you expect to be stronger? based on your answer, provide a reaction of the selected stronger acid forming a carboxylate ion #3arrow_forward
