How many equivalents are in H2SO4?
two equivalents
Thus one mole of H2SO4 donates two moles of H+ ions and contains two equivalents of H2SO4.
How do you calculate the weight of H2SO4?
Molar mass of H2SO4
Look for the atomic masses of hydrogen, sulfur and oxygen. Hence, molecular weight of H2SO4 is 98.08 g/mol.
What is the equivalent weight of H2SO4 in the reaction H2SO4 Nai?
The answer is 49+12.25=61.25 but I don’t know,how?
What is molecular weight of H2SO4?
98.079 g/mol
Sulfuric acid/Molar mass
How do you find equivalent weight?
The equivalent weight of an element is its gram atomic weight divided by its valence (combining power).
What is the basicity of H2SO4?
two
Since the formula of sulphuric acid is H2SO4, two H ions can be released from the acid molecule. Hence, basicity is 2.
What is the N factor of H2SO4?
N factor of an acid or a base is the number of H+ ions or OH- ions it donates in a reaction. in case of h2so4 number of H+ ions it donates is 2. hence n factor is two.
How do you find the normality of H2SO4?
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).
What is the equivalent weight of CaCO3?
The equivalent mass of CaCO3 is 100g/2=50g. Thus,The equivalent mass of Calcium Carbonate is 50g.
What is the equivalent weight of h2o2?
The molar mass of hydrogen peroxide is 34g. So, the gram equivalent weight of hydrogen peroxide is calculated using the molar mass and change in oxidation number. The gram equivalent weight of hydrogen peroxide as reductant is 17g. Therefore, the equivalent weight is 152g .
What is normality of 98% H2SO4?
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 0.04 m H2SO4?
Here the N-Factor is 2.
How do you calculate 1N H2SO4?
If you took 6.9 mL of concentrated sulfuric acid and diluted it to 250 mL, you would have a 1 N H2SO4 solution. (Important note: Always add the acid (or base) to water, in that order. Pour slowly with constant mixing. This will help prevent rapid heat generation and spattering of the mixture.
What is the normality of 0.5 m H2SO4?
0.1 N
– Therefore the normality of the resulting solution (diluted sulphuric acid) is 0.1 N.
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 make 2M H2SO4?
So you take 900 ml of plain water, add your 100ml of concentrated H2SO4. Mix all this together and you now have 2 moles of H2SO4 in 1L of solution…. that is 2M H2SO4. You can use the formula as described to create whatever volume of solution you want however if you don’t want a liter.
How do you make 5n H2SO4?
Answer
- Normality of acid solution = Molarity of solution x Basicity of Acid. Basicity of H2SO4 is 2, as 2H+ ions are obtained per molecule in the aqueous state from H2SO4. 5 = Molarity x 2. …
- Molarity = (moles of H2SO4)/(liters of solution) 2.5 = (moles of H2SO4) / 0.25. …
- Hence, 0.625 moles of conc. H2SO4 is needed.
