An anion is an atom that has A. Gained one or more electrons.
Answer: Homogeneous mixtures : food coloring dissolved in water, a cup of tea and sugar :
Heterogeneous mixtures : food coloring dissolved in water, a cup of tea and sugar
Explanation:
Mixture is a substance which has two or more components which do not combine chemically and do not have any fixed ratio in which they are present.
Homogeneous mixtures : It is a mixture that has uniform composition throughout the solution and the particle size or shapes are not different.
There is no physical boundary between the dispersed phase and dispersion medium. Example: peanuts and almonds mixed together in a bowl, a bucket full of sand and gravel
Heterogeneous mixtures : It is a mixture that has non-uniform composition throughout the solution and the particle size or shapes are also different.
There is a physical boundary between the dispersed phase and dispersion medium. Example: food coloring dissolved in water, a cup of tea and sugar
Answer:
decrease the molar solubility of the solid relative to its molar solubility in pure water.
Explanation:
The common ion effect is defined as a decrease in the solubility of a solute because of the addition of a second solute with which it has a common ion. If a solution already contains a solute MX and another ionic solid containing BX is added to the solution, the X^- anion is common to the both species. Hence the presence of MX will decrease the solubility of BX compared to the solubility of BX in pure water.
Generally, when a soluble ionic solid is placed in a solution containing a common ion, the molar solubility of the solid decreases compared to its molar solubility in pure water.
