- Each box represents an acid solution at equilibrium. Squares represent H+ ions, and circles represent the anion. Water molecules are not shown. Which figure represents a strong acid? Which figure is a weak acid?arrow_forwardAre the concentrations of hydronium ion and hydroxide ion in a solution of an acid or a base in water directly proportional or inversely proportional? Explain your answer.arrow_forwardConsider two separate solutions: one containing a weak acid. HA, and one containing HCl. Assume that you start with 10 molecules of each. a. Draw a molecular-level picture of what each solution looks like. b. Arrange the following from strongest to weakest base: Cl- H2O. A- . Explain.arrow_forward
- In each of the following chemical equations, identify the conjugate acid—base pairs. a. HF(aq)+H2O(l)F-(aq)+H3O+(aq)b. CN(aq)+H2O(l)HCN(aq)+OH(aq) c. HCO3-(aq)+H2O(l)H2CO3(aq)+OH-(aq)arrow_forwardHow do the components of a conjugate acid—base pair differ from one another4? Give an example of a conjugate acid—base pair to illustrate your answer.arrow_forwardYou are asked to determine whether an unknown white solid is acidic or basic. You also need to say whether the acid or base is weak or strong. You are given the molar mass of the solid and told that it is soluble in water. Describe an experiment that you can perform to obtain the desired characteristics of the white solid.arrow_forward
- Both HF and HCN ionize in water to a limited extent. Which of the conjugate bases. F“ or CN”, is the stronger base? See Table 14.2.arrow_forwardList the following bases in order of their decreasing strength strongest base first: CN,H2O,HSO3,ClO,Cl.arrow_forwardArsenic acid (H3AsO4) is a moderately weak triprotic acid. Write equations showing its stepwise dissociation. Which of the three anions formed in these reactions will be the strongest Brnsted base? Which will be the weakest Brnsted base? Explain your answers.arrow_forward
