What is the concentration of Concentrated HCl?
Dilutions to Make a 1 Molar Solution
| Concentrated Reagents | Density | Molarity (M) |
|---|---|---|
| Hydrochloric acid 36% | 1.18 | 11.65 |
| Hydrochloric acid 32% | 1.16 | 10.2 |
| Hydrofluoric acid 40% | 1.13 | 22.6 |
| Nitric acid 70% | 1.42 | 15.8 |
How do you calculate Concentrated HCl?
To obtain the Molarity of Concentrated acid, this simple formula can be applied: %purity*specific gravity*10 divided by Molar mass of the acid.
What is the mass of a concentrated solution of HCl?
The correct density of concentrated hydrochloric acid is 1.19 g/cm3 .
What is the molarity of 35% HCl?
35.453+1.0079=36.4609 g/mol . 1.18 gmL ⋅1000mL 1 L ⋅1 L =1180 g . Thus, 35% w/w for HCl puts it at 413 g HCl1180 g soln . which is sensible considering how 37% is close to 12 M .
What is the equivalent weight of HCl?
The equivalent weight of an acid or base for neutralization reactions or of any other compound that acts by double decomposition is the quantity of the compound that will furnish or react with or be equivalent to 1.008 g of hydrogen ion or 17.0074 g of hydroxide ion—e.g., hydrochloric acid (HCl), 36.461 g; sulfuric …
How do you find the mass of a concentrated solution?
Calculating Mass Concentration
- Step 1: Identify the mass of the solute.
- Step 2: Identify the volume of solution.
- Step 3: Divide the mass of the solute by the volume of solution to find the mass concentration of the solution.
What volume of concentrated HCl contains 125g of HCl?
Concentrated hydrochloric acid has concentration of 12.19 mol/litre, The molar mass of HCl is 36.458 g/mol. 125 g is therefore (125/36.458) = 3.4286 moles. So the volume that would contain this number of moles is going to be (3.4286 / 12.19) = 0.28126 litres or 281.26 ml.
