(Solved): 1-3 please 1. Write a balanced chemical equation for the neutralization reaction of oxalic acid with ...

1. Write a balanced chemical equation for the neutralization reaction of oxalic acid with sodium hydroxide. \[ \begin{array}{c} 2 \mathrm{NaOH}+\mathrm{H}_{2} \mathrm{O}_{4} \mathrm{C}_{2} \cdot 2 \mathrm{H}_{2} \mathrm{O} \rightarrow \mathrm{Na}_{2} \mathrm{O}_{4} \mathrm{C}_{2}+4 \mathrm{H}_{2} \mathrm{O} \\ m_{M}=126.07 \frac{9}{m_{0}} \end{array} \] 2. Calculate the range of molarities of \( \mathrm{NaOH} \) solutions that will be made by the class based on the mass range of \( \mathrm{NaOH} \) you will be using in this lab. [assume \( 0.500 \mathrm{~L} \) of total solution] 3. Why is it necessary to standardize a \( \mathrm{NaOH} \) solution? (Why do you not know a precise molarity if you use a precise mass balance?)
