Question

when 0.5 mole of phosphoric acid is dissolved in aqueous solution how many moles of -ve and +ve ions are collected altogether?​

Answer 1

Explanation:

Simple my lovelies

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
