Concept explainers
(a)
Interpretation:
Strong acid, weak acid, strong base and weak base to be identified for the given reaction.
Concept Introduction:
Strong Acid is an acid which gives or releases proton readily in the solution while weak acid looses proton with increase in concentration of the solution.
Strong base radilly releases hydroxyl ion in the solution while weak base not releases hydroxyl ion readily in the solution.

- Problem 1: The following equations describe how our circulatory and respiratory systems remove carbon dioxide. An enzyme, carbonic anhydrase, plays a role in this process by speeding up the rate at which carbon dioxide hydrolyzes: CO2+ H,0 -- H,CO, (a) And the rate at which H,CO, ionizes is: H,CO a) + H,Om- HCO, (a) + H,O" (ag) If the concentration of HCO, is 0.028M and the concentration of CO, is 2.7 x 10 M, what is the pH of the blood? (Note: H2co3 is dissolved co2).arrow_forwardProblem 4 Complete these acid-base equations. Use the curved arrow method to show the electron movement in the reactions. (a) :NH, (b) CH₂O: H₂O H₂O conjugate acid : NH3 conjugate acid CH₂OH + conjugate base HO: conjugate base H₂Oarrow_forward1 Which of the following statements about acid strength is true? Multiple Choice The stronger the acid, the further the equilibrium lies to the left. The stronger the acid, the smaller the Ka. The stronger the acid, the larger the pka. The stronger the acid, the smaller the pka.arrow_forward
