Draw three-beaker sets similar to those in WorkPatch 15.3 for Problems 15.91 and 15.92. Fill in the species present in each beaker. Assume the H₂SO₄ dissociates completely to give two H₃O⁺ ions (although it actually doesn’t do this).

Workpatch 15.3

What species are present in each beaker?

Ionic compounds are often called salts. What are the chemical formula and name of the salt that gives rise to the salt solution in beaker 3?

Data from Problem 15.91

How many moles of Ba(OH)₂ does it take to neutralize 0.50 mole of H₂SO₄? Why does the resulting solution after the neutralization no longer conduct electricity? Why does the solution then conduct electricity after an excess of Ba(OH)₂ is added?

Data from Problem 15.92

How many moles of Ba(OH)₂ does it take to neutralize 2.5 moles of HNO₃?
