(a)
Interpretation:
The statement related to the dissolution of the given ionic solid in water is whether related to the term hydrated ion, hydrogen atom or oxygen atom has to be determined.
Concept Introduction:
Solubility is the quantity of solute (solid, liquid or gas) that will dissolve in a given amount of solvent (solid, liquid or gas) at definite temperature and pressure. Solubility depends on the physical and chemical property of solvent, solute and concentration of the solution.
Three factors which affect the rate of solution formation are given below:
- The state of subdivision of the solute.
- The degree of agitation during solution preparation.
- The temperature of the solution components.
(b)

The pieces of potato were initially the same weight, shape, and size. Each potato piece was submerged into a beaker containing one of the sucrose concentrations for 30 minutes. The final weight of the potato was measured and recorded in the table. Which TWO conclusions can be correctly drawn from this data? A In the 0.4 mol/dm3 solution, the sucrose molecules moved across the semi-permeable membrane to go from a lower solute concentration (the potato) to a higher solute concentration (the sucrose solution), leading to a decrease in the weight of the potato. B In the 1 mol/dm3 solution, the water molecules moved across a semi-permeable membrane to go from a lower solute concentration (the potato) to a higher solute concentration(the sucrose solution), leading to a decrease in weight of the potato. C In the 0.8 mol/dm3 solution, the sucrose molecules moved…arrow_forwardAnswer the following about drawing the attractive force between a water molecule (H2O) and an ammonium ion (NH4*).
