Solutions:- Part 3 – Solutions with various examples

• Here are some of the examples of various solutions commonly used in the clinical laboratory.

0.1 M Hydrochloric acid solution

• This is 0.1 moles of HCl in one liter of solution.
• It is 3.65 g/1000 mL.

1 M solution of H₂SO₄

• This 1 molar solution = 98.08 g H₂SO₄ / L of the solution.

1 mol HCl/L

• Take 88 ml of concentrated HCl and add make a solution to one liter with water.

1 M solution of sodium chloride NaCl

• The gram-molecular weight is derived by finding the sum of the atomic weight:
• Na = 23
• Cl = 35.5
• Gram-molecular weight = 58.5
• 58.5 g of NaCl is dissolved in one liter (58.5 g/L).

10% solution of Na₂SO₄

• This is a weight/volume solution.
• 10 g/100 mL
