which statement is true?
Answers
The true statement is:
Some solids are more soluble and some are less soluble in water. (option C)
Solubility of a Substance
- Solubility is defined as the maximum amount of a substance that can be dissolved in a solvent at a particular temperature.
- Solubility follows the simple rule- "like dissolves like". This implies that polar solvents dissolve polar substances and likewise for non-polar solvents.
- Generally, solubility increases with an increase in temperature.
Solubility of Solids in Water
- As stated above, solubility depends on temperature and the type of solute.
- Solids like salt, sugar, and coffee can dissolve in water at room temperature.
- However, solids like sand and pepper cannot dissolve in water even at elevated temperatures.
- This difference is due to the particles of the solid and the interparticle interactions of the solute and solvent.
Therefore, the correct option is C. Some solids are more soluble and some are less soluble in water.
Answer:
Concept:
The ability of a material, the solute, to create a solution with another substance, the solvent, is known as solubility in chemistry. Insolubility refers to the inability of a solute to form such a solution. The concentration of a solute in a saturated solution, in which no more solute can be dissolved, is used to determine the extent of a substance's solubility in a certain solvent. The two compounds are said to be at solubility equilibrium at this moment. Some solutes and solvents may have no such limit, in which instance the two compounds are be "miscible in any quantity."
Given:
which statement is true
[A]. In water, all substances are equally soluble.
[B]. In water, most substances are similarly soluble.
[C]. In water, some substances are more solubility and others are less soluble.
[D]. all solids are insoluble in water
Answer:
The correct answer is option [c]
In water, some substances are more solubility and others are less soluble.
If the solvent is water, that is a polar solvent, the absorption of the substance is determined by its polarity. The solubility of a material is proportional to its polarity, or the ease at which it can split into and - fractions.
Water does not dissolve all compounds. Why are some chemicals soluble in water while others are not? It's to do with the structure of the water molecule. Because oxygen attracts electrons more strongly than either hydrogen, the shared electrons (bonded electrons) spend much more time near oxygen than either hydrogen.
