Question

when 0.5 moles of phosphoric acid is dissolved in an aqueous solution,how many moles of +ve and -ve ion are collected altogether? (assuming complete dissociation)

Answer 1

Answer:

These are acids that can produce more than one H+ ions when dissolved in water. H2CO3 and H2SO3 are called diprotic acids, and H3PO3 and H3PO4 are called triprotic acids. HF, HCl, HBr, and HC2H3O2 are examples of monoprotic acids. The dissociation of polyprotic acids usually occurs in steps.

Answer 2

Explanation:

Multiplied no of moles to avagadros number first to get the number of particles

0.5×6.02×10^23 = 3.01×10^23 Molecular formula for phosphoric acid is H3PO4

According to balance eq

H3PO4

Ratio is

3:1

For H+ ions

3×3.01×10^23= 9.01×10^23 no of +ve of ions

For PO4

1×3.01×10^23= 3.01×10^23 no _ve ions

Total number of ions altogether is

3.01×10^23+ 9.01×10^23

= 1.204×10^24 ions

Or

1.204×10^24÷6.02×10^23

= 2.0 moles
