Classify each oxide as acidic, basic, or amphoteric and explain.MgOK2OMnO4–Fe2O3NO2

The reaction of calcium hydride, CaH2, with water can be characterized as a Lewis acid-base reaction: CaH2(s)+2H2O(l)Ca(OH)2(aq)+2H2(g) Identify the Lewis acid and the Lewis base among the reactants. The reaction is also an oxidation-reduction reaction. Identify the oxidizing agent, the reducing agent, and the changes in oxidation number that occur in the reaction.

Which is the stronger acid, H2SO4 or H2SeO4? Why? You may wish to review the Chapter on acid-base equilibria.

All the following salts are alkaline except   LiClO   NH4NO3   SrCrO4   K2HPO4

Amphoteric oxides are compounds that exhibit both acidic and basic behavior. True or False

List the following compounds in order of increasing acid strength: HBrO, HBrO2, HClO2

Write the acidic equilibrium equation for HONH3 +

Calculate the pH for a 0.200 M KClO2 aqueous solution. (Ka for HClO2 is 1.1× × 10–2).

What is the pH of a 0.22M NaH2PO4 solution?

7. Explain the following statements: HCIO3 is a stronger acid than HBRO3 b. A Ca(OH)2 solution will give a higher pH compared to a KOH solution at the same concentration and temperature. (Assume both substances are completely dissolved). a.
