Thank you very much. Your video tutorial is easy to comprehend. Please I have a question, I would be glad if you could help me. Produce 500mL 10% dextrose in 0.9% NaCl. Available components are ; 250mL 50% dextrose 500mL normal saline 500mL 5% dextrose 2 bottles of 3% NaCl (30mL)
Thank u very much sir. In the aspect of arrangement of the concentrations you arranged the higher concentrations for the first question and the last question you arranged the second higher concentration to the lower concentration which makes the answers differ, I wanted to know if it is correct to do it at any arrangement
Why is the proportion included for the 50 % solution in the final ratio when the mixture of the 70% and 20% already achieves the 30% of the desired mixture
On the first example for three components, how did you decide that the difference of 50- 30 and 70-30 is to be added? Why couldn't other differences be added instead? I'm confused on this part.
Thank you Jaztyne for watching and for the comment. To determine the number of parts of the 20% solution, you subtract the desired concentration (30%) from the higher concentration. In this question, there are two higher concentrations. So, we subtract the 30% from the 50% and the 70% and then we add them to determine the number of parts of the 20% solution. An important rule regarding the alligation method is that the desired concentration must always be between the higher concentration and the lower concentration. That is why we have the 50, 30, 20 combination and the 70, 30, 20 combination. Hope this helps.
thanks so much for this video. Please I have a question from the last calculation does that mean that the numbers are arranged in order of the highest first? like how you arranged the 95 70 60? not that the 70 was meant to be btwn the 60 and 50?
Thank you Adura for watching and for the comment. Regarding your question, the desired concentration must always be between the closest higher concentration and the closest lower concentration. So if our desired concentration was 55% instead of 70%, then the 55% is between the 60% and the 50%. Hence, we will arrange it as 95 60 55 50. Hope this helps. Keep up the good work.
Glad you found the video helpful Ross. Whenever you are altering the concentration of a product, the desired concentration must always be between the concentration of the components you are mixing. Hence, at least one component must have a higher concentration than the desired concentration and at least one component must have a lower concentration. If it appears from a question that the desired the concentration is lower than the lowest given concentration then it is likely that there is another component usually a diluent (e.g., water) which has a concentration of zero. Hope this helps. Let me know if you need more clarification. Thank you for watching and for the comment.

Thank you so much, but the last example why do you have to calculate 95 and 60 first, why not 60 and 50?
The arrangement on the grid is in a decreasing order of concentration.
