It has lost electrons as electrons are negatively charged particles, hence a loss of electrons will leave the rod positively charged.
Answer : 42.3 ml of a 0.266 M solution are required.
Solution : Given,
Molarity of solution 1 = 0.266 M
Molarity of solution 2 = 0.075 M
Volume of solution 2 = 150 ml = 0.150 L (1 L = 1000 ml)
Formula used :
where,
= Molarity of solution 1
= Molarity of solution 2
= Volume of solution 1
= Volume of solution 2
Now put all the given values in above formula, we get
(1 L = 1000 ml)
Therefore, 42.3 ml of a 0.266 M solution are required.
