- At 25°C, the Ka of pentafluorobenzoic acid (C6F5COOH) is 0.033. Suppose 0.100 mol of pentafluorobenzoic acid is dissolved in 1.00 L of water. What is the pH of this solution?arrow_forwardLithium diisopropylamide (LDA) is used as a strong base in organic synthesis. LDA is itself prepared by an acid-base reaction between butyllithium and N,N-diisopropylamine, [(CH3)2CH]2NH. Write an equation for this reaction, and place the appropriate labels on each reagent and product from the following list: stronger acid, stronger base, weaker acid, weaker base.arrow_forwarda) b) What is the conjugate acid of NH3? What is the conjugate base of H2O?arrow_forward
- In equilibrium, label the stronger acid, the stronger base, the weaker acid, and the weaker base. Also estimate the position of equilibrium.arrow_forwardWhich of the following two acids has the stronger conjugate base? Nitrous acid, Ka = 7.1 x 10–4 Phenol, Ka = 1.0 x 10–10 The strength of the conjugate base cannot be obtained from the information given. Nitrous acid, because it has a larger Ka value. Nitrous acid, because it has a smaller Ka value. Phenol, because it has a larger Ka value. Phenol, because it has a smaller Ka value.arrow_forwardWhich statement correctly explains why H2S is a stronger acid than water? Sulfur (S) has a larger atomic size than oxygen (0), so HS- is a more stable, strong acid than OH-. Sulfur (S) has a larger atomic size than oxygen (0), so HS- is a more stable, weaker base than OH-. Sulfur (S) has a larger atomic size than oxygen (0), so H2S is a more stable, weaker base than H20. Sulfur (S) has a larger atomic size than oxygen (0), so H2S is a more stable, stronger acid than H20. What is the pH of a 1x10-4 mol HCI solution? 1 poin hparrow_forward
