VERY SHORT ANSWER TYPE QUESTIONS :- 1) What are the two components of a solution? 2) How can you convert a saturated solution into an unsaturated solution? 3) What is meant buy concentration of a solution? 4) Give one example of homogeneous mixture. 5) Give one example of suspension. 6) What is tincture iodine?
Answers
Answer:
1) The two components of solution are solute (the object dissolved) and solvent (the object that dissolves).
2) By heating the solution a saturated solution can be changed into an unsaturated solution.
3) In chemistry, concentration is the abundance of a constituent divided by the total volume of a mixture. Several types of mathematical description can be distinguished: mass concentration, molar concentration, number concentration, and volume concentration. A concentration can be any kind of chemical mixture, but most frequently solutes and solvents in solutions. The molar (amount) concentration has variants such as normal concentration and osmotic concentration.
4) Examples of homogeneous mixtures include air, saline solution etc.
5) Common examples of suspension include the mixture of chalk and water, muddy water.
6) Tincture of iodine, iodine tincture, or weak iodine solution is an antiseptic. It is usually 2 to 7% elemental iodine, along with potassium iodide or sodium iodide, dissolved in a mixture of ethanol and water. Tincture solutions are characterized by the presence of alcohol. It was used from 1908 in pre-operative skin preparation by surgeon Antonio Grossich.
