A monohydrogen is compound that contains one hydrogen. For example HPO2-ion is the formula for monohydrogen phosphate and water is at times referred to as dihydrogen monoxide.
Al2(HPO4)3 Aluminum has ionic charge of +3 and monohydrogen phosphate has -2 because phophate has valance of -3 and has -2 when it was as monohydrogen phophate
Zinc monohydrogen phosphate
monohydrogen phosphate
Na2HPO4
CaHPO4
Sodium Monohydrogen Phosphate heptahydrate, Sodium phosphate dibasic heptahydrate
PO43- (phosphate) is the conjugate base of HPO42- (monohydrogen phosphate)
Ammonium monohydrogen phosphate: (NH4)2HPO4 Ammonium dihydrogen phosphate: NH4H2HPO4
CH4 --> 3H+ + CH3- : monohydrogen carbane (carbanion)
The chemical name is Cobalt (III) phosphate.
Strontium monohydrogen phosphate is SrHPO4 . The phosphate anion has a '3-' negative charge. So it needs cations with a total charge of '+3'. Strontium being a Group 2 element has a cationic charge of '+2' . So the third '+' charge is made up of an 'H^+' cation. Hence the name 'mono-' for the hydorgen. 'Mono' means 'one(1)'.
Baking powder (sodium monohydrogen carbonate, or -bicarbonate) could be added.
