How do you make orthophosphoric acid?
It can be conveniently prepared by dissolving P2O5 in water followed by boiling the solution to form a thick syrup. Red phosphorus when heated with conc. HNO3 yields orthophosphoric acid.
How do you make 1 M phosphoric acid?
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 6M NaOH?
6M NaOH solution is made by dissolving 6 mols of NaOH in 1 liter of H2O. NaOH has a molar mass of 39.9997 g/mol so for a 6M solution, we need 240 g NaOH (39.997 x 6) in 1L of H2O. This is an exothermic reaction so use caution.
How do you make 6n HCl from concentrate?
If you want to make a 6 N HCl solution, you need to dilute concentrated HCl (36\%, 11.65 N) with approximately 50 \% water. The actual math is add 5.15 ml concentrated HCl to 4.85 ml water.
What is the basicity of orthophosphoric acid?
In the case of orthophosphoric acid, we will see a number of hydrogen atoms connected to the oxygen for calculating its basicity. The number of H atoms bonded to the oxygen atoms in the above compound is equal to 2. Therefore, the basicity of the orthophosphorous acid is 2. Hence the correct option is B.
When orthophosphoric acid is heated?
When orthophosphoric acid (H3PO4) is heated and dehydration takes place. It form metaphosphoric acid (HPO_3).
What percent HCl is 6M?
6M HCl has half the concentration of 12M HCl, therefore a solution that is 50\% 12M HCl, is a 6M solution.
What does 6M solution mean?
Another way to refer to the “richness” of the acid is by the term Molarity, M. The molarity of a solution tells the number of moles of solute per liter of total solution. 6M HCl means that every 1 liter of solution holds 6 moles of dissolved HCl.
