How to make molar solution?
A balance and a volumetric flask are used to make molar solutions. A procedure for making a molar solution with a 100 ml volumetric flask is as follows: 1 Calculate the weight of solute needed to make 100ml of solution using the above formula. 2 Weigh out amount of solute needed using a balance. 3 Transfer the solute to a clean, dry 100ml volumetric flask. 4 Add distilled water slowly to the volumetric flask. Wash all the solute into the bottom of the flask as you do so. Keep adding water until you reach the 100ml mark on the neck of the flask. 5 Place the stopper in the flask and gently swirl the flask until all the solute is dissolved.
What is the most abundant solution?
Solutions can exist as solids, liquids, or gases. All solutions contain a solvent and one or more solutes. The solvent, often water, is the chemical that’s most abundant. The solute is the chemical (s) that’s less abundant.
How to dissolve a chemical?
Stir the solution until all of the chemical dissolves. Break up hard lumps of chemical with a mortar and pestle or by careful crushing in a plastic bag with a hammer. Chemicals dissolve more quickly by gently heating the solution and stirring.
How long to dissolve solutes in solid form?
Plan one hour for every 2-4 solutions you need to prepare.
