Sulphuric acid is generally available in market as 18.0M solution. How would you prepare
250ml of 0.50M aqueous H2SO4? (Ans- 243.06ml)
Answers
Answer:
A 1 M solution of anything is a solution that contains 1 mole of the compound dissolved in 1 L of solvent. I assume this will be 1 M H2SO4 in water. So, to make up this solution, get a 1 L volumetric flask and to it add about 500 mL of water. Then, slowly, added 98.079 g (or 53.3 mL) of sulfuric acid.
Preparation and Standardization of 0.25 M Ethanolic Sulphuric...
Add slowly, with stirring, 13.9 ml of sulphuric acid to 900 ml ethanol.
Make up the volume with ethanol to produce 1000 ml.
Allow the solution to cool down.
Standardize the solution before use.
To determine how many grams of sulfuric acid you will need, you will first need to calculate the equivalent mass of H2SO4. This is the gram-formula weight divided by the number of acid hydrogens in the compound. It is 98/2 = 49. Then you can calculate the amount of grams of H2SO4 that are needed.
