A solution of permanganate is standardized by titration with oxalic acid, . To react completely with mol of oxalic acid required
Zielflug [23.3K]

Answer:

M=0.120M

Explanation:

Hello,

In this case, the undergone chemical reaction is:

MnO_4^-(aq)+H_2C_2O_4(aq)\rightarrow Mn^{+2}+CO_2

In such a way, the acidic redox balance turns out:

(Mn^{+7}O_4)^-+5e^-+8H^+\rightarrow Mn^{+2}+4H_2O\\H_2C_2O_4\rightarrow2CO_2+2H^++2e^-

Which leads to the total balanced equation as follows:

2(MnO_4)^-(aq)+6H^+(aq)+5H_2C_2O_4(aq)\rightarrow2Mn^{+2}(aq)+8H_2O(l)+10CO_2(g)

Thus, as the mass of oxalic acid is not given, one could suppose a value of 1 g (which you can modify based on the actual statement) in order to compute the oxalic acid moles as shwon below:

1gH_2C_2O_4*\frac{1molH_2C_2O_4}{90.04gH_2C_2O_4} *\frac{2mol(MnO_4)^-}{5molH_2C_2O_4} =0.00444mol(MnO_4)^-

Whereby the molality results:

M=\frac{0.00444mol(MnO_4)^-}{0.03702L} =0.120M

Remember you can modify the oxalic acid mass as you desire.

Best regards.

Select the correct answer.
Nikitich [7]

Ans: 4.73 moles

Given reaction:

2LiBr + Ba → BaBr2 + 2Li

Mass of Ba = 325 g

Atomic mass of Ba = 137.32 g/mol

# moles of Ba = 325/137.32 = 2.368 moles

Based on the reaction stoichiometry:

1 mole of Ba produces 2 moles of Li

Therefore, 2.368 moles of Ba will produce, 2.368*2 = 4.736 moles
