Answer : The molarity of the new solution is, 4.069 M
Solution : Given,
Molarity of KOH solution = 4 M
Volume of KOH solution = 2.5 L
Volume of water added = 1.8 L
First we have to calculate the volume of new solution.
Volume of new solution = volume of KOH solution + volume of water added
Volume of new solution = 2.5 L + 1.8 L = 4.3 L
Now we have to calculate the molarity of the new solution.
Formula used :
where,
= molarity of KOH solution
= molarity of new solution
= volume of KOH solution
= volume of new solution
Now put all the given values in the above formula, we get the molarity of the new solution.
Therefore, the molarity of the new solution is, 4.069 M

Answer:
Consequently, what happens when gas obtained by heating slaked lime and ammonium chloride is passed through copper sulphate solution? The HCl in the gas mixture will form hydrochloric and the H+ will react with some of the NH3(aq), forming NH4^+, and with some of the SO4^2-, forming HSO4^-.
