What are the necessary steps to form a solution?

Posted August 26, 2024


Answer

The necessary steps to form a solution are described below:

  1. Determine solution volume and concentration: Identify how concentrated the solution needs to be and the quantity of it required.
  2. Calculate the mass of the solute: Use concentration and volume equations to find out how much solute is needed. Use the following 2 equations: 
    1. Concentration Equation: Concentration (M) = Moles of Solute/ Volume of Solution (L) 
    2. Mass to Moles Equation: Moles of Solute = Mass of Solute (g) / Molar Mass (g/mol)
  3. Transfer solute to flask: Place the measured solute into a volumetric flask. 
  4. Add initial water: Fill the flask about halfway with distilled water.
  5. Dissolve the solute: Stopper the flask and shake it gently until the solute is fully dissolved. Then continue adding distilled water to the flask until it is nearly at the marked line.
  6. Adjust to exact volume: Use a pipette to carefully add distilled water until the liquid level reaches the line on the flask.
  7. Final mixing: Stopper the flask again, shake it gently to ensure thorough mixing and invert it ten to twelve times.
