The minimum effective concentration of sodium hypochlorite solution for disinfection purposes is typically around 0.1% to 0.5%. However, the specific concentration needed may vary depending on the target microorganism and the level of contamination present.
To produce 1L of 10% ammonia solution from 25% ammonia solution, you need to dilute the 25% solution by adding a calculated amount of water. To do this, you can calculate the volume of the 25% solution needed and the volume of water needed using the formula: C1V1 = C2V2, where C1 is the initial concentration (25%), V1 is the initial volume, C2 is the final concentration (10%), and V2 is the final volume (1L).
To make a 2% solution from a 25% solution, you need to dilute it. Let x ml be the amount of water needed. Using the equation for mass balance: 0.25(40) = 0.02(40 + x), solve for x to find that x = 875 ml of water needs to be added.
.80x+.30y=400*.62 .80x+.30y=248 This is equation one. x+y=400 x=400-y This is the second equation. .80(400-y)+.30y=248 320-.80y+.30y=248 -.50y=-72 Y=144 X=256 CHECK .80(256)+.30(144)=400(.62) 204.8+43.2=248 248=248
To dilute a 25% glucose and glutamic acid solution, you would mix the solution with an appropriate amount of water. The exact amount of water needed will depend on the desired final concentration of the solution. Calculate the amount of water needed based on the volume and concentration of the original solution.
You would need 6.15 kg of calcium hypochlorite powder at 65% strength to make 200 liters of 2% hypochlorite solution.

To determine the amount of hypochlorite needed to produce a 100 mg/L chlorine solution in 300 gallons of water, you need to calculate the total chlorine required. The total amount of chlorine needed is 100 mg/L x 300 gallons = 30,000 mg of chlorine. Knowing that hypochlorite contains about 12-15% available chlorine, you can divide 30,000 mg by 0.15 to get the total amount of hypochlorite required.
