How do you make 6mm phosphoric acid?
For example, to make 500 mL of 6M HCl, use 250 mL of concentrated acid and slowly dilute to 500 mL with water….Recipes for Acid Solutions.
| Name / Formula / F.W. | Concentration | Amount/Liter |
|---|---|---|
| sp. gr. 1.42 | 0.1 M | 6.3 |
| Phosphoric Acid | 6 M | 405 mL |
| H3PO4 | 3 M | 203 |
| F.W. 98.00 | 1 M | 68 |
What volume of concentrated phosphoric acid and of water would be required to prepare 500ml of 1/4 solution?
You would add 34 mL of 85 \% phosphoric acid to enough distilled water to make a total of 500 mL.
What is the molecular weight of phosphoric acid?
97.994 g/mol
Phosphoric acid/Molar mass
How do you find the molarity of phosphoric acid?
1 gram of H3PO4 will be equal to 1/98 moles. Therefore, we can say that 1 liter of Phosphoric acid contains 14.615 moles or in other words molarity of 85\% (w/w) Phosphoric acid is equal to 14.615 M….Known values.
| Known values | |

| Concentration of Phosphoric acid solution | 85\% (\% by mass, wt/wt) |
How do you make 6 molar HCl?
6M HCl has half the concentration of 12M HCl, therefore a solution that is 50\% 12M HCl, is a 6M solution. To make 0.5L of 6M HCl, you would need 0.25 (half of 0.5) litres of 12M HCl.
How do you make 6N H2SO4?
How to prepare 6M H2SO4 in a laboratory – Quora. 6 M H2SO4 will be 6 moles or 6 × 98 =588 g of H2SO4 per Litre solution. So you should have to add around 650 g of acid into 200 mL of water slowly so that over heating and spilling does not occur.
How do you make phosphoric acid solution?
This solution is infinitely soluble in water or alcohol; it is soluble at 1 part in 8 of a 3:1 (v/v) ether:alcohol mixture. 2 The pH of a 0.1 N aqueous solution is approximately 1.5. 2 Approximately 67.8 mL are required to prepare 1 L of 1.0 M phosphoric acid.
How do you make 0.5 phosphoric acid?
For one liter of the 0.5 N: 1000 mL x 0.5 N = V (mL) x 45.6 N. Thus, we measure 10.96 mL (almost 11 mL) of the stock acid and add it to 100-200 mL of water mix it and the dilute the mixture up to one liter to have a final concentration of 0.5 N.
How phosphoric acid is formed?
Phosphoric acid may be obtained by adding sulphuric acid to the phosphate of baryta suspended in water. The sulphuric acid unites with the baryta forming an insoluble salt which precipitates while the phosphoric acid remains in solution.
What is the molecular weight of ortho phosphoric acid?

What is the molecular formula of phosphoric acid?
Phosphoric acid PubChem CID 1004 Structure Find Similar Structures Chemical Safety Laboratory Chemical Safety Summary (LCSS Molecular Formula H3PO4 or H3O4P Synonyms Phosphoric acid 7664-38-2 ORTHOPHOSPHORI
What is the dot classification for phosphoric acid?
DOT Classification : Class 8: Corrosive material Identification : Phosphoric acid (Phosphoric Acid) UNNA: 1805 PG: III Special Provisions for Transport: Not available. 15. Other Regulatory Information Federal and State Regulations:
How do you make phosphoric acid from phosphorus pent oxide?
The )to 5000°F 3000) phosphorus pent oxide is then hydrated with dilute H3PO4 or water to produce strong phosphoric acid liquid (Reaction 3). Demisting, the final step, removes the phosphoric acid mist from the combustion gas stream before release to the atmosphere.
