For the following reaction, 76.0 grams of barium chloride are allowed to react with 67.0 grams of potassium sulfate.
The reaction consumes _____ moles of barium chloride. The reaction produces _____ moles of barium sulfate and _____ moles of potassium chloride.
Answer: a) The reaction consumes 0.365 moles of barium chloride.
b) The reaction produces 0.365 moles of barium sulfate and 0.730 moles of potassium chloride.
Explanation:
To calculate the moles :
According to stoichiometry :
1 mole of 
require 1 mole of 
Thus 0.365 moles of will require=
of
Thus is the limiting reagent as it limits the formation of product and is the excess reagent.
As 1 moles of give = 1 moles of 
Thus 0.365 moles of give = of
As 1 moles of give = 2 moles of 
Thus 0.365 moles of give =
of
Thus the reaction consumes 0.365 moles of barium chloride. The reaction produces 0.365 moles of barium sulfate and 0.730 moles of potassium chloride.
Answer:
Balanced net ionic equation;
2MnO₄⁻ + 16H⁺ + 5C₂O₄²⁻ → 2Mn²⁺ + 8H₂O + 10 CO₂
Explanation:
- This is an example of a redox titration where acidified potassium permanganate (KMnO₄) is titrated against oxalic acid (H₂C₂O₄).
- A redox reaction is a type of reaction that involves both reduction and oxidation.
- One reactant of the reaction gains electrons(reduction) while another loses electrons(oxidation).
- During the redox reaction, H⁺/KMnO₄ undergoes reduction while the oxalic acid undergoes oxidation.
- Therefore, KMnO₄ is the oxidizing agent while H₂C₂O₄ is the reducing agent.
- The net ionic reaction will be;
2MnO₄⁻ + 16H⁺ + 5C₂O₄²⁻ → 2Mn²⁺ + 8H₂O + 10 CO₂
- From the reaction, MnO₄⁻ is reduced to 2Mn²⁺ while C₂O₄²⁻ is oxidized to CO₂.
- Therefore, two moles of KMnO₄ will react with 5 moles of oxalic acid.
All the hydrohalic acids are equally strong because of the leveling effect.
<h3>
What is leveling effect?</h3>
- The effect of solvent on the properties of acids and bases is Leveling effect or solvent leveling
- The strength of a strong acid will be limited ("leveled") by the basicity of the solvent. Similarly, the strength of a strong base will be leveled by the acidity of the solvent.
- When a strong acid is dissolved in water, it reacts with it to form hydronium ion (H3O+).
- An example of this would be the following reaction, where "HA" is the strong acid: HA + H2O → A⁻ + H3O⁺
