Chapter 20: Problem 56

Trisodium phosphate (TSP) is an effective grease remover. Like many cleaners, TSP acts as a base in water. Write a balanced equation to account for this basic behavior.

Short Answer

Expert verified
The balanced equation that accounts for the basic behavior of Trisodium Phosphate (TSP) in water is: \( Na_{3}PO_{4} (s) + H_{2}O (l) \rightarrow 3 Na^{+} (aq) + HPO_{4}^{2-} (aq) + OH^{-} (aq) \)

Step by step solution

01

Write the formula for trisodium phosphate

Trisodium phosphate (TSP) has the chemical formula Na3PO4.
02

Dissociation of trisodium phosphate in water

When trisodium phosphate dissolves in water, it dissociates into sodium ions (Na+) and phosphate ions (PO4^3-). We can write the dissociation equation as: Na3PO4 (s) -> 3 Na+ (aq) + PO4^3- (aq)
03

Basic behavior of trisodium phosphate

The basic behavior of TSP comes from the phosphate ion (PO4^3-), which can act as a Brønsted-Lowry base by accepting hydrogen ions (H+) from water (acting as an acid). The reaction can be written as: PO4^3- (aq) + H2O (l) -> HPO4^2- (aq) + OH- (aq)
04

Balanced equation for the basic behavior of trisodium phosphate

The balanced equation that accounts for the basic behavior of TSP can be obtained by combining the dissociation equation (Step 2) and the basic behavior equation (Step 3). Na3PO4 (s) -> 3 Na+ (aq) + PO4^3- (aq) PO4^3- (aq) + H2O (l) -> HPO4^2- (aq) + OH- (aq) Therefore, the balanced equation is: Na3PO4 (s) + H2O (l) -> 3 Na+ (aq) + HPO4^2- (aq) + OH- (aq)

The electrolysis of aqueous sodium chloride (brine) is an important industrial process for the production of chlorine and sodium hydroxide. In fact, this process is the second largest consumer of electricity in the United States, after the production of aluminum. Write a balanced equation for the electrolysis of aqueous sodium chloride (hydrogen gas is also produced).

Hydrazine is somewhat toxic. Use the following half-reactions to explain why household bleach (highly alkaline solution of sodium hypochlorite) should not be mixed with household ammonia or glass cleansers that contain ammonia. \(\mathrm{ClO}^{-}+\mathrm{H}_{2} \mathrm{O}+2 \mathrm{e}^{-} \longrightarrow 2 \mathrm{OH}^{-}+\mathrm{Cl}^{-} \quad \mathscr{E}^{\circ}=0.90 \mathrm{~V}\) \(\mathrm{N}_{2} \mathrm{H}_{4}+2 \mathrm{H}_{2} \mathrm{O}+2 \mathrm{e}^{-} \longrightarrow 2 \mathrm{NH}_{3}+2 \mathrm{OH}^{-} \quad \mathscr{E}^{\circ}=-0.10 \mathrm{~V}\)

Write balanced equations describing the reaction of \(\mathrm{Sr}\) with each of the following: \(\mathrm{O}_{2}, \mathrm{~S}, \mathrm{Cl}_{2}, \mathrm{P}_{4}, \mathrm{H}_{2}, \mathrm{H}_{2} \mathrm{O}\), and \(\mathrm{HCl}\).

Give the Lewis structure, molecular structure, and hybridization of the oxygen atom for \(\mathrm{OF}_{2}\). Would you expect \(\mathrm{OF}_{2}\) to be a strong oxidizing agent like \(\mathrm{O}_{2} \mathrm{~F}_{2}\) discussed in Exercise \(67 ?\)

What is a disproportionation reaction? Use the following reduction potentials $$ \begin{aligned} \mathrm{ClO}_{3}^{-} &+3 \mathrm{H}^{+}+2 \mathrm{e}^{-} \longrightarrow \mathrm{HClO}_{2}+\mathrm{H}_{2} \mathrm{O} & & \mathscr{E}^{\circ}=1.21 \mathrm{~V} \\ \mathrm{HClO}_{2}+2 \mathrm{H}^{+}+2 \mathrm{e}^{-} \longrightarrow \mathrm{HClO}+\mathrm{H}_{2} \mathrm{O} & & \mathscr{E}^{\circ}=1.65 \mathrm{~V} \end{aligned} $$ to predict whether \(\mathrm{HClO}_{2}\) will disproportionate.
