7 (a) Describe what happens when each of the following molecules is separately dissolved in water and illustrate with an equation in each case: ethanoic acid (CH3COOH) ammonia (NH3)

`What products are yielded in nearly every acid/base neutralization reaction? salt and carbon dioxide water and salt carbon dioxide and water Oil and water or none of these

Fill in the Blanks Type your answers in all of the blanks and submit When sulfurous acid, H2SO4 is dissolved in water it undergoes stepwise dissociation, initially giving up its first proton the in the reaction: H2SO3(aq) + H20(aq) = H30 (aq) + HSO, (aq) The resulting HSO, (aq) species is amphoteric in solution and can thus react with water as either an acid or as a base. The equilibrium expressions below show these 2 scenarios. Identify whether HSO, (aq) behaves as an acid or as a base in these reactions. HSO (aq) + H20(1) = H,SO3(aq) + OH (aq) In this reaction HSO, acts as a/an Type your answer here HSO (aq) + H2O(1) = So, (aq) + H;0 (aq) In this reaction HSO, acts as a/an Type your answer here

7 (a) Describe what happens when each of the following molecules is separately dissolved in water and illustrate with an equation in each case: (i) ethanoic acid (CH₂COOH) (ii) ammonia (NH3) (b) Identify the conjugate acids and bases in the substances mentioned in question 7(a) above. (c) Explain the difference between: (i) a strong acid and weak acid and (ii) a strong base and a weak base

The active ingredient of bleach such as Clorox is sodium hypochlorite (NaClO). Its conjugate acid, hypochlorous acid (HClO), has a Ka of 3.0 × 10–8. (a)The undiluted bleach contains roughly 1 M NaClO. Calculate the pH of 1 M NaClO solution.  (b)Some applications require extremely diluted bleach solution, such as swimming pools. Suppose the solution in (a) is diluted by 10,000 -fold. Calculate the pH of the diluted solution, and demonstrate that you can still neglect the autoionization of water in your calculation.  (c)Suppose the solution in (a) is diluted by 1million-fold, briefly explain how your approach will be different. Write the equation with [H3O+] as the unknown, but you do not need to solve it.

Which of the following reactions is an acid-base reaction? A) AGNO:(aq) + KF(aq) → AgF(s) + KNO:(aq) B) NH:(aq) + HF(aq) → NH:"(aq) + -F(aq) C) NO: (aq) + AI(s) → NH3(g) + AIO: (aq) D) CH:(g) + 202(g) - 2H:O(g) + CO:(g)

Consider the reaction below. Co(H,O),* (aq) + 4 Cl¯ (aq) = COC1," (aq) + 6 H,O (1I) The equilibrium constant expression (K) of the reaction does not include the concentration of H,O even though the reaction produces six moles of water. Explain.
