pl. suggest how to prepare 50 sulphuric acid
Yes, sulphuric acid will freeze at a temperature below 10 degrees Celsius (50 degrees Fahrenheit). At this temperature, the liquid will solidify into a crystalline form.
To prepare a 0.5 M acetic acid solution using a 2.5 M stock solution, you will need to dilute it. The formula for dilution is C1V1 = C2V2, where C1 is the initial concentration, V1 is the initial volume, C2 is the final concentration, and V2 is the final volume. Plugging in the values, you will need 20 ml of the 2.5 M stock solution to make 100 ml of a 0.5 M acetic acid solution.
To prepare a 6M hydrochloric acid solution, you would need to dilute the concentrated hydrochloric acid. The volume of concentrated acid required would depend on its concentration. However, assuming the concentrated acid is 12M, you would need to mix 25 cm3 of the concentrated acid with 25 cm3 of water to prepare 50 cm3 of 6M HCl solution using the formula M1V1 = M2V2.
50% citric acid powder = 50 g citric acid/100 g 4% citric acid solution = 4 g citric acid/100 ml distilled water Determining how much citric acid powder to use is based upon how much citric acid solution you wish to make. To make 100 ml of solution, you should use 8 g of powder.
Reagents Needed: diphenyl carbazide conc. HCl ethanol Method: 1. Dissolve 0.5g of diphenyl carbazide in 5mL of conc HCl. 2. Prepare a solution of 50%(v/v) ethanol by mixing 50mL 95%(v/v) ethanol and water. 3. Transfer the diphenyl carbazide solution in HCl to the 50% ethanol and mix.
Yes, sulphuric acid will freeze at a temperature below 10 degrees Celsius (50 degrees Fahrenheit). At this temperature, the liquid will solidify into a crystalline form.
Preparation of standards Prepare a stock uric acid solution of 100 mg/L. Dilute it to give working concentrations of 10, 20, 30, 40, 50 and 60 mg/L. Procedure:1 Prepare a 100 mg/L stock solution of uric acid Weigh out 100 mg uric acid, transfer it to a 1 L volumetric flash, add about 900 ml distilled water, and then add about 100 µl of 0.6 N NaOH to help dissolve the uric acid. Make up to the volume with water when uric acid is fully dissolved.2 Dilute the stock solution to give working concentrations of 10, 20, 30, 40, 50, 60 mg/L. To prepare 50 ml of the working standards 5, 10, 20, 30, 40, 50 mg/L respectively, weigh 10, 15, 20, 25, 30 g of stock solution into 50 ml volumetric flasks and make up to volume with distilled water.

A 50 ml solution that is 10% acid will consist of 5 ml of acid (10% of the volume) and 45 ml of water (90% of the volume). You're not adding any water, but you want to add enough acid to make a solution that is 50% acid and 50% water. You will need to have a total of 45 ml of acid in the mixture to make it a 50/50 solution, since the amount of water is also 45 ml. You have 5 ml in there already, so you would need to add 40 ml of acid. That would make a total 90 ml solution that is 50% water (45 ml) and 50% acid (45 ml).
50% acid in a 6 gallon solution means that 3 gallons are acid. 9 gallons more acid will give you a total of 12 gallons of acid in a 15 gallon solution. 12 is 80% of 15.
6 litres of 50% + 4 litres of 25%
t = number of liters of 30% acid solution s = number of liters of 60% acid solution t+s=57 .30t+.60s=.50*57 t=57-s .30(57-s)+.60s=.50*57 .30*57 -.30s +.60s = .50*57 .30s = .50*57 - .30*57 = .20*57 s = .20*57/.30 = 38 liters of 30% solution t = 57 - s = 57-38 = 19 liters of 60% solution

50% citric acid powder = 50 g citric acid/100 g 4% citric acid solution = 4 g citric acid/100 ml distilled water Determining how much citric acid powder to use is based upon how much citric acid solution you wish to make. To make 100 ml of solution, you should use 8 g of powder.
pH less than 7
To get a 2% acid solution, you need to dilute the 50% acid solution with water. Since the final volume is 2 gallons, you will need to mix 2 gallons of water with the 2 gallons of 50% acid solution to get a 2% acid solution.
