Short Answer

Expert verified
a. Lithium oxide (\(\mathrm{Li}_{2} \mathrm{O}\)) forms a basic solution, as shown by the reaction: \[\mathrm{Li}_{2} \mathrm{O} \ + \ 2\mathrm{H}_{2}\mathrm{O} \ \rightarrow \ 2\mathrm{LiOH} \] b. Carbon dioxide (\(\mathrm{CO}_{2}\)) forms an acidic solution, as shown by the reaction: \[\mathrm{CO}_{2} \ + \ \mathrm{H}_{2}\mathrm{O} \ \rightleftharpoons \ \mathrm{H}_{2}\mathrm{CO}_{3} \] c. Strontium oxide (\(\mathrm{SrO}\)) forms a basic solution, as shown by the reaction: \[\mathrm{SrO} \ + \ \mathrm{H}_{2}\mathrm{O} \ \rightarrow \ \mathrm{Sr(OH)}_{2} \]

Step by step solution

01

Determine the type of oxide for each substance

We will determine the type of oxide for each substance. Metallic oxides are basic and non-metallic oxides are acidic. a. \(\mathrm{Li}_{2} \mathrm{O}\): Lithium oxide Lithium is a metal, so this is a metallic oxide. b. \(\mathrm{CO}_{2}\): Carbon dioxide Carbon is a non-metal, so this is a non-metallic oxide. c. \(\mathrm{SrO}\): Strontium oxide Strontium is a metal, so this is a metallic oxide.
02

Write reactions for each substance dissolving in water

Next, we will write the reactions for each substance dissolving in water. a. Lithium oxide (\(\mathrm{Li}_{2} \mathrm{O}\)): \[ \mathrm{Li}_{2} \mathrm{O} \ + \ 2\mathrm{H}_{2}\mathrm{O} \ \rightarrow \ 2\mathrm{LiOH} \] Since \(\mathrm{LiOH}\) is a strong base, the solution will be basic. b. Carbon dioxide (\(\mathrm{CO}_{2}\)): \[ \mathrm{CO}_{2} \ + \ \mathrm{H}_{2}\mathrm{O} \ \rightleftharpoons \ \mathrm{H}_{2}\mathrm{CO}_{3} \] Carbonic acid (\(\mathrm{H}_{2}\mathrm{CO}_{3}\)) is a weak acid, so the solution will be acidic. c. Strontium oxide (\(\mathrm{SrO}\)): \[ \mathrm{SrO} \ + \ \mathrm{H}_{2}\mathrm{O} \ \rightarrow \ \mathrm{Sr(OH)}_{2} \] Since \(\mathrm{Sr(OH)}_{2}\) is a strong base, the solution will be basic.
03

Determine the type of solution for each oxide

Now we have the reactions for each oxide dissolving in water, we can determine the type of solution they form: a. Lithium oxide (\(\mathrm{Li}_{2} \mathrm{O}\)) forms a basic solution. b. Carbon dioxide (\(\mathrm{CO}_{2}\)) forms an acidic solution. c. Strontium oxide (\(\mathrm{SrO}\)) forms a basic solution.

Papaverine hydrochloride (abbreviated papH \(^{+} \mathrm{Cl}^{-} ;\) molar mass \(=378.85 \mathrm{~g} / \mathrm{mol}\) ) is a drug that belongs to a group of medicines called vasodilators, which cause blood vessels to expand, thereby increasing blood flow. This drug is the conjugate acid of the weak base papaverine (abbreviated pap; \(K_{\mathrm{b}}=\) \(8.33 \times 10^{-9}\) at \(35.0^{\circ} \mathrm{C}\) ). Calculate the \(\mathrm{pH}\) of a \(30.0-\mathrm{mg} / \mathrm{mL}\) aqueous dose of papH \(^{+} \mathrm{Cl}^{-}\) prepared at \(35.0^{\circ} \mathrm{C} . K_{\mathrm{w}}\) at \(35.0^{\circ} \mathrm{C}\) is \(2.1 \times 10^{-14}\).
