Answered step-by-step

Problem 144 Hard Difficulty

A useful application of oxalic acid is the removal of rust $\left(\mathrm{Fe}_{2} \mathrm{O}_{3}\right)$ from, say, bathtub rings according to the reaction $$\begin{aligned}
\mathrm{Fe}_{2} \mathrm{O}_{3}(s)+6 \mathrm{H}_{2} \mathrm{C}_{2} \mathrm{O}_{4}(a q) & \longrightarrow \\&
2 \mathrm{Fe}\left(\mathrm{C}_{2} \mathrm{O}_{4}\right)_{3}^{3-}(a q) &+3 \mathrm{H}_{2} \mathrm{O}+6 \mathrm{H}^{+}(a q)
\end{aligned}$$
Calculate the number of grams of rust that can be removed by $5.00 \times 10^{2} \mathrm{mL}$ of a $0.100 \mathrm{M}$ solution of oxalic acid.

Properties Of Solutions - Intro

In chemistry, a solution is a homogeneous mixture composed of two or more substances. The term "solution" is also used to refer to the resultant mixture. The solution is usually a fluid. The particles of a solute are dispersed or dissolved in the solvent. The resulting solution is also called the solvent. The solvent is the continuous phase.
