10 liters
A chemist has one solution which is 50 percent acid and a second solution which is 25 percent acid how much of each should be mixed to make a 10 liters of a 40 percent acid solution?
6 litres of 50% + 4 litres of 25%
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 do you prepare 200 ppm formaldehyde solution from percent 37 formalin solution?
200 ppm solution means 200 mg/liter 200 mg = (100 *0.2)/37 = 0.540 g of 37% formaldehyde Vol of 0.540 g of 37 % formaldehyde= 0.540/1.09 = 0.496 mL of 37 % of formaldehyde Therefore: 0.496 mL/1 liter.

How does one prepare 10 percent neutral buffered formalin?
To prepare 10 percent neutral buffered formalin, start by mixing 90 mL of distilled water with 10 mL of formaldehyde solution (37-40% concentration). Add buffering agents, typically sodium phosphate monobasic (3.6 g) and sodium phosphate dibasic (4.4 g), to maintain neutral pH. Adjust the final volume to 1 liter with distilled water, ensuring thorough mixing. It's essential to use appropriate safety precautions, as formaldehyde is a hazardous substance.
