Dilutions to Make a 1 Molar Solution
| Concentrated Reagents | Density | Normality (N) |
|---|---|---|
| Perchloric acid 70\% | 1.67 | 11.6 |
| Orthophosphoric acid 85\% | 1.7 | 45.6 |
| Sodium hydroxide 47\% | 1.5 | 17.6 |
| Sulfuric acid 98\% | 1.84 | 36.8 |
What is the normality of 98\%?
The normality of 98\% H2SO4 solution is nearly (d = 1.6 g/ml)
What is the molality of 98 H2SO4 by weight?
Molality (mole(solute)/kg(solvent))- Assume an identical solution wherein there is 1000g of solvent. Thus here we will have the mass of H2SO4= 49000g (since, in this solution solute (H2SO4)is 98\% and solvent thus is 2\%). So, number of moles of H2SO4= 49000/98= 500. So , Molality = 500 mole/kg.
How do you find the Normality of H2SO4 solution?
If you know the Molarity of an acid or base solution, you can easily convert it to Normality by multiplying Molarity by the number of hydrogen (or hydroxide) ions in the acid (or base). For example, a 2 M H2SO4 solution will have a Normality of 4N (2 M x 2 hydrogen ions).
How do you calculate Normality of H2SO4?
Use this formula: mol. weight / basicity (or n factor), giving you 49.03. Then, find normality using the weight of solute x 1000 / equivalent weight x volume of solution in ml, which would ultimately give you 12.26 grams. Therefore, you have to use 12.26 g of H2SO4 to prepare your 10 N concentrated H2SO4 solution.
What is the relation between Normality and Molarity of a given solution of H2SO4?
Normality by multiplying Molarity by the number of hydrogen (or hydroxide) ions in the acid (or base). For example, a 2 M H2SO4 solution will have a Normality of 4N (2 M x 2 hydrogen ions).
How do you find the Molarity of H2SO4?
Expert Answer:
- Mass of solute in 100ml of solution = 90 g of H2SO4
- Moles = Mass of solute in 100ml in solution = 90 = 0.9183. Molar mass 98.
- Volume = mass X density.
- Wt of 100ml of solution = 100 X 1.8 = 180 g.
- Solution = solvent + solute.
- 180= x + 90.
- x = 180 -90 = 90 g.
- Molarity = No.
