The electron negativity of a compound is 2 & 4. Find its heat of formation.

Discuss the metallurgy of nuclear grade thorium?

13.4 g of a sample of unstable hydrated salt: Na2SO4. xH20 was found to contain 6.3g of water. Determine the number of water of crystallization

Chemical properties of metal.

How would you distinguish between the solutions of chlorine in water and hydrogen chloride in water?

How to calculate the ph of the complete ionization of phosphoric acid?
How to calculate the ph of an acid?

H3PO4 ---------> H2PO4- + (H+) Ka1 = 7.5x10^-3

H2PO4- --------> HPO4-2 + (H+) Ka2 = 6.2x10^-8

HPO4 -2 -------> PO4 -3 + (H+) Ka3 = 4.8x10^-13

calculate the ph of one molar solution of H3PO4 that is completely ionized? (by using the 3 equation to find the pH) . How different will be the ph from irregular calculation (which is by using the first equation to find the pH).
