Question

- What is the concentration of NO, ions when equal
volumes of 0.1 M AgNO, and 0.1 M NaCl are
mixed together?
(1) 0.1 N
(2) 0.25 M
(3) 0.05 M
(4) 0.2 M​

Answer 1

Answer:

(c ) is correct

Explanation:

given 0.1 M of agno3

i.e 0.1 moles of AgNo3 in 1000 ml or 1 litre

AgNo3 has ag3+ ions and no3- ion

i.e 0.1 moles of no3- ions

similarly 0.1 M of nacl means 0.1 moles of nacl in 1000 ml or 1 litre

molarity of no3 ions = no. of moles / volume of sol.

= 0.1/2

= 0.05 M
