How to prepare 50 ppm ammonia solution form 25% ammonia
solution?
Answer Posted / dinesh solanki
25% ammonia means 25*10000 ppm = 25*10000=250000 ppm
Take 1mL from 25% Ammonia solution ---> 100mL (2500ppm)
Again dilute 2mL to 100mL with water (50ppm)
In short 1mL to 100mL with water and from that 2mL to 100mL with water.

2. Two grams of Benzoic acid are dissolved in 200 ml of water and extracted with 200 ml of diethyl ether. The distribution coefficient of benzoic acid is 100, and its dissociation constant is 6.5 10-5. Calculate the distribution ratio (D) of benzoic acid at pH 2, 5, and 6. 3. Calculate D at pH 2 to 10 (1 unit apart) in the above problem, and plot D versus pH.
