12*(90%)=10.8=X*.25
10.8/.25=X=43.2
43.2-12=31.2

How many ml should be added to 100ml of a 25 percent solution to get produce a 20 percent solution?
add 25ml more of solution x * 20 = 100 * 25 x = 25
How many liters of water must be added to 30 liters of 20 percent ALCOHOL solution to dilute it to a15 percent solution?
You have 6 litres of alcohol in 24 litres of water You need to add x litres to make 6 equal to 15% of 30 + x. 6 is 15% of 40, so x = 10
How many liters of a 7 percent solution of salt should be added to a 19 percent solution in order to obtain 456 liters of a 15 percent solution?
This is an algebra problem. There will be 2 equations and 2 unknowns. Let x = amount of 7% solution, and y = amount of 19% solution. .07x + .19y = .15*456. x + y = 456; or x = 456-y which will substitute into the first equation. .07(456-y) +.19y = .15*456. 31.92-.07y+.19y = 68.4. .12y = 36.48. y = 304L (amount of 19% solution to add). x = 456-y. x = 456 - 304. x = 152L (amount of 7% solution to add).
How many liters of pure antifreeze must be added to 30L of 60 percent antifreeze solution to obtain a 75 percent solution?
60% solution contains 6/10 x 30 ie 18 litres 18 + A = 3/4 (30 + A) 72 + 4A = 90 + 3A 4A - 3A = 90 - 72 A = 18 ie add another 18 litres, giving 36 litres out of 48 which is the required 75%.
What number produces an irrational number when added to 13?
Any irrational number, when added to 13, will produce an irrational number.
Why KI is to be added to prepare to prepare iodine solution?
KI is potassium iodide, you'd react it with something to produce iodine ions. It reacts as reducing agent

What is the organic compound that reacts when iodine is added to starch solution?
starch
What is the role of potassium iodide in the formulation of strong iodine solution?
The role of KI in the preparation of strong iodine solution is to enhance the solubility of iodine crystals in water. Iodine is generally not soluble in water. The KI is added to help the iodine to be dissolved. -College Chemistry professor
What does lugol's iodine?
it is iodine and potassium iodide solution It's a orange colored solution that consists of Iodine and Potassium Iodide and is used to test a substance for starch. If the color of the solution turns black when put on/in the substance, then the substance is positive for starch.

Why does glycogen change to red when iodine solution is added?
Iodine tests for complex sugars. Glycogen is a complex sugar and will change dark purple when iodine solution is added (color is irrelevant, all you really need to know is that the change to a specific color signifies a presence of a macro molecule)
