How to prepare 50 ppm ammonia solution form 25% ammonia solution?..

Answer / vani

First convert ppm to %.i.e.50ppm/10,000=0.005%
Then apply c1v1=c2v2;
c1=25%;v1=volume to be taken from 25% solution;
c2=0.005%; v2=100ml
v1=c2v2/c1
=0.005x100/25
=0.02ml
=20┬ÁL

How to prepare 50 ppm ammonia solution form 25% ammonia solution?..

Answer / greg

Convert % to ppm. This is probably faster.

Ammonia Solution
1% = 10000ppm
25% = 250000 (25/100 = 0.25 X 1000000)


C1V1 = C2V2
C1 = 50 ppm (target solution concentration)
V1 = 100 mL (targer solution volume)

C2 = 250000 ppm (stock solution concentration)
V2 = X (stock solution volume required)

V2 = 0.02 mL diluted to 100mL in a volumetric flask

How to prepare 50 ppm ammonia solution form 25% ammonia solution?..

Answer / qamaruddin

25%AMMONIA MEANS 25g in 100 ml.
above solution 0.25g/ml or 250mg/ml.
250mg of 25% ammonia solution in 100ml=2.5mg/ml
and dilute 2ml(2.5mg/ml sol)in 100ml = 0.05mg/ml.
0.05mg/ml is equal to 50ppm.

How to prepare 50 ppm ammonia solution form 25% ammonia solution?..

Answer / 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.

How to prepare 50 ppm ammonia solution form 25% ammonia solution?..

Answer / pavan

25%AMMONIA MEANS 25g in 100 ml.
convert in to mg/ml.
25000mg in 100 ml (i.e2500ppm)
take 2ml of 25%ammonia and dilute to 100 ml that is equal
to 50ppm.
