Interpretation:
The ion left in the reaction after completion of the reaction needs to be determined.
Concept introduction:
When barium nitrate is reacted with potassium phosphate, barium phosphate and potassium nitrate is produced.
Answer to Problem 8STP
D
Explanation of Solution
Given:
Molarity of
Volume of
Molarity of
Volume of
Calculations:
Moles of
=
Molar mass of
=261 g/mol
Mass of
=6.525g
Moles of
=
Molar mass of
=212 g/mol
Mass of
=4.24 g
The reaction is given as:
According to reaction:
261 g
So, 6.525 g
=5.3 g
But
Whole of
So, after reaction the ions present should be barium nitrate and phosphate.
Mathematical calculation shows that option D is correct and rest options are wrong.
