Concept explainers
(a)
Interpretation:
The reaction occurs when Sulphuric acid is added to
(b)
Interpretation:
The balanced reaction between triiodide and sulphate has to be written.
Concept introduction:
- There is a law for conversion of mass in a
chemical reaction i.e., the mass of total amount of the product should be equal to the total mass of the reactants. - The concept of writing a balanced chemical reaction is depends on conversion of reactants into products.
- First write the reaction from the given information.
- Then count the number of atoms of each element in reactants as well as products.
- Finally obtained values could place it as coefficients of reactants as well as products.
(c)
Interpretation:
Concentration of sulphite in the wine has to be calculated. The answer should be expressed in mol/L and in
Concept introduction:
Molarity (M):
Molarity is one of the concentration unit. Molarity is defined as number of moles of the solute in one litre of solution.
(d)
Interpretation:
Are the results given in the statement significantly different at 95% confidence level has to be identified.
