Answer:
Explanation:
Hello,
In this case, since the acid is monoprotic, we can notice a 1:1 molar ratio between, therefore, for the titration at the equivalence point, we have:
Thus, solving for the moles of the acid, we obtain:
Then, by using the mass of the acid, we compute its molar mass:
Regards.
Answer:
There is a basic difference, because mass is the actual amount of material contained in a body and is measured in kg, gm, etc. Whereas weight is the force exerted by the gravity on that object mg. Note that mass is independent of everything but weight is different on the earth, moon, etc.
Answer:
Net ionic equation: 2I⁻(aq) + Cr²⁺(aq) → CrI₂(s)
<h3>
Explanation:</h3>
- A chemical equation shows chemical symbols of compounds known as reactants and compounds known as products in a chemical reaction.
- The chemical equation between hydroiodic acid and chromium (II) carbonate is given by;
2HI(aq) + CrCO₃(aq) → H₂CO₃(aq) + CrI₂(s)
- The Ionic equation is an equation that shows all the ions involved in a chemical reaction.
- In this case, the ionic equation is;
2H⁺ I⁻(aq)+ Cr²⁺ CO₃²⁻(aq) → 2H⁺ CO₃²⁻(aq) + CrI₂(s)
- The net ionic equation is an equation showing only the ions that take part in the reactions. The ions that do not take part in the chemical reaction known as spectator ions are not shown when writing net ionic equations.
- Spectator ions are those ions that do not change state after the chemical reaction has taken place. In this case, hydrogen ions and carbonate ions are spectator ions.
- The net ionic equation is
2I⁻(aq) + Cr²⁺(aq) → CrI₂(s)
Number of millimoles of NaOH consumed in present titration =<span>33.23 X 0.09892
= 3.287
Thus, number of millimoles of vinegar present in sample = 3.287
Now, Molarity of vinegar solution = </span>
<span> = </span>
<span> = 0.1222 mol/dm3
Molar concentration of vinegar present in sample solution is 0.1222 M </span>
