In the reaction of a weak acid and a weak base there is no spectator ion. Since there are no spectator ions, the total ionic and the net ionic are exactly the same. Example HF and NH 3. General Equation. HF(aq) + NH3(aq) → NH4F(aq) Total Ionic Equation. HF(aq) + NH3(aq) → NH + 4 (aq) + F − (aq) Net Ionic Equation. Weak bases. Ammonia is a typical weak base. Ammonia itself obviously doesn't contain hydroxide ions, but it reacts with water to produce ammonium ions and hydroxide ions. \[ NH_{3(aq)} + H_2O_{(l)} \rightleftharpoons NH^+_{4(aq)} + OH^-_{(aq)}\] The solution pH is then calculated using the concentration of hydroxide ion: n (OH Acid-base indicators are either weak organic acids or weak organic bases. The equilibrium in a solution of the acid-base indicator methyl orange, a weak acid, can be represented by an equation in which we use HIn as a simple representation for the complex Since acetic acid is a weak acid, its conjugate base is strong enough to react with water. So the acetate anion is a strong enough base to react with water. And when acetate anion reacts with water, it forms acetic acid and hydroxide ions. Since the concentration of hydroxide ions in solution have increased, that's what makes the solution basic. Ammonia is a weak base and Potassium hydroxide is a strong base, then then the solution of potassium hydroxide will always have a higher pH than a solution of ammonia, therefore the correct answer is option C. . What is a Chemical compound? A chemical compound is a combination of two or more either similar or dissimilar chemical elements.. As given in the problem, ammonia is a weak base. The buffer is extremely effective at resisting a change in pH because the added hydroxide ion attacks the weak acid (in very high concentration) rather than the hydronium ion (in very low concentration). The major effect of the addition of the hydroxide ion is thus to change the ratio of acid to conjugate base, i.e., to change the value of OSZs.
