EXPLANATION

• A solution is a homogenous mixture in which the substance is a small quantity known as a solute and dissolved into another substance called a solvent.
• The state of the solution is usually governed by the phase of the solvent which is in the larger quantity.
• In a true solution, the particles of the solute can not be seen from the naked eye.
• Soda water is an example of Gas in liquid type of solution in which carbon dioxide is dissolved in water.
• The tincture of Iodine is an example of liquid in liquid type of solution in which the solution is made by adding elemental iodide as a solute to a solvent made by adding equal parts of water and ethanol(alcohol). Tincture of Iodine is used as an antiseptic.
• Saltwater is an ionic solution in which salt is dissolved as a solute in water(solvent).
• Black ink is an example of suspension in which solid particles of dye are suspended in a liquid phase.
