Chapter 13: Problem 35

Write balanced equations that describe the following reactions. a. the dissociation of perchloric acid in water b. the dissociation of propanoic acid \(\left(\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{CO}_{2} \mathrm{H}\right)\) in water c. the dissociation of ammonium ion in water

Short Answer

Expert verified
a. \( \mathrm{HClO}_{4}(\mathrm{aq}) + \mathrm{H}_{2} \mathrm{O}(\mathrm{l}) \rightarrow \mathrm{H}_{3} \mathrm{O}^{+}(\mathrm{aq}) + \mathrm{ClO}_{4}^{-}(\mathrm{aq}) \) b. \( \mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{CO}_{2} \mathrm{H}(\mathrm{aq}) + \mathrm{H}_{2} \mathrm{O} (\mathrm{l}) \rightarrow \mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{CO}_{2}^{-}(\mathrm{aq}) + \mathrm{H}_{3}\mathrm{O}^{+}(\mathrm{aq}) \) c. \( \mathrm{NH}_{4}^{+}(\mathrm{aq}) + \mathrm{H}_{2}\mathrm{O}(\mathrm{l}) \rightarrow \mathrm{NH}_{3}(\mathrm{aq}) + \mathrm{H}_{3}\mathrm{O}^{+}(\mathrm{aq}) \)

Step by step solution

01

Identify the chemical formulas of the reactants and products.

In this case, we have perchloric acid dissociating in water. The chemical formula of perchloric acid is HClO4, and water is H2O.
02

Write the balanced equation for the dissociation of perchloric acid in water.

The dissociation of perchloric acid in water can be written as: $$ \mathrm{HClO}_{4}(\mathrm{aq}) + \mathrm{H}_{2} \mathrm{O}(\mathrm{l}) \rightarrow \mathrm{H}_{3} \mathrm{O}^{+}(\mathrm{aq}) + \mathrm{ClO}_{4}^{-}(\mathrm{aq}) $$ b. the dissociation of propanoic acid in water
03

Identify the chemical formulas of the reactants and products.

In this case, we have propanoic acid dissociating in water. The chemical formula of propanoic acid is \( \mathrm{CH}_{3} \mathrm{CH}_{2}\mathrm{CO}_{2} \mathrm{H} \), and water is \( \mathrm{H}_{2}\mathrm{O}\).
04

Write the balanced equation for the dissociation of propanoic acid in water.

The dissociation of propanoic acid in water can be written as: $$ \mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{CO}_{2} \mathrm{H}(\mathrm{aq}) + \mathrm{H}_{2} \mathrm{O} (\mathrm{l}) \rightarrow \mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{CO}_{2}^{-}(\mathrm{aq}) + \mathrm{H}_{3}\mathrm{O}^{+}(\mathrm{aq}) $$ c. the dissociation of ammonium ion in water
05

Identify the chemical formulas of the reactants and products.

In this case, we have the ammonium ion dissociating in water. The chemical formula of the ammonium ion is \( \mathrm{NH}_{4}^{+} \), and water is \( \mathrm{H}_{2}\mathrm{O}\).
06

Write the balanced equation for the dissociation of ammonium ion in water.

The dissociation of ammonium ion in water can be written as: $$ \mathrm{NH}_{4}^{+}(\mathrm{aq}) + \mathrm{H}_{2}\mathrm{O}(\mathrm{l}) \rightarrow \mathrm{NH}_{3}(\mathrm{aq}) + \mathrm{H}_{3}\mathrm{O}^{+}(\mathrm{aq}) $$

What mass of KOH is necessary to prepare \(800.0 \mathrm{mL}\) of a solution having a \(\mathrm{pH}=11.56 ?\)

Consider 0.10 \(M\) solutions of the following compounds: \(\mathrm{AlCl}_{3}, \mathrm{NaCN}, \mathrm{KOH}, \mathrm{CsClO}_{4},\) and NaF. Place these solutions in order of increasing \(\mathrm{pH}\).

Codeine \(\left(\mathrm{C}_{18} \mathrm{H}_{21} \mathrm{NO}_{3}\right)\) is a derivative of morphine that is used as an analgesic, narcotic, or antitussive. It was once commonly used in cough syrups but is now available only by prescription because of its addictive properties. If the \(\mathrm{pH}\) of a \(1.7 \times 10^{-3}-M\) solution of codeine is \(9.59,\) calculate \(K_{\mathrm{b}}\)

Rank the following 0.10 \(M\) solutions in order of increasing pH. a. \(\mathrm{NH}_{3}\) b. KOH c. \(\mathrm{HC}_{2} \mathrm{H}_{3} \mathrm{O}_{2}\) d. KCl e. HCl

The pH of \(1.0 \times 10^{-8} M\) hydrochloric acid is not \(8.00 .\) The correct \(\mathrm{pH}\) can be calculated by considering the relationship between the molarities of the three principal ions in the solution \(\left(\mathrm{H}^{+}, \mathrm{Cl}^{-}, \text {and } \mathrm{OH}^{-}\right) .\) These molarities can be calculated from algebraic equations that can be derived from the considerations given below. a. The solution is electrically neutral. b. The hydrochloric acid can be assumed to be \(100 \%\) ionized. c. The product of the molarities of the hydronium ions and the hydroxide ions must equal \(K_{\mathrm{w}}\) Calculate the \(\mathrm{pH}\) of a \(1.0 \times 10^{-8}-M\) HCl solution.
