A0.100-l sample of an unknown hno3 solution required 32.9 ml of 0.200 m ba(oh)2 for complete neutralization. what was the concentration of the hno3 solution?

0.132 M

Explanation:

According to the neutralization law,

where,

= molarity of solution = ?

= volume of solution = 0.100 L = 100 ml (1L=1000ml)

= molarity of solution = 0.200 M

= volume of solution = 32.9 ml

= valency of = 1

= valency of = 2

Therefore, the concentration of solution is 0.132 M

the energy to form plasma comes from heat or electricity in the atmosphere!
