1.	How much water should be added to 500 mL of N/2NaOH solution to obtain a decinormal solution?
Answer» SOLUTION : Suppose, X mL of WATER are required to be added for dilution. According to the law of equivalence, `underset("Conc. Sol")(N_(1)V_(1)) = underset("Dil. Sol")(N_(2)V_(2))` For concentrated (given) solution, `N_(1) = 1/2, V_(1) = 500 mL` For diluted solution, `N_(2) = 1/10` (DECINORMAL), `V_(2) = 500 +x` Therefore, according to the above equation `1/2 xx 500 = 1/10 xx (500 +x)` or x = 2000 mL Hence, 2000 mL of water should be added to obtain a decinormal solution.
