How do you prepare 60 percent sulphuric acid solution?
0.2g Na2CO3 dissolved into 25ml DI Water. Methyl Orange is used 2 to 3 drops is a indicator. then we take normal solution of 0.02N H2SO4 in beurate . note the volume consumed of H2SO4. put these value in formula formula N H2SO4= wt of Na2CO3 * volume of Na2CO3 used/ 53 * volume of H2SO4 consumed repeat this process

How do you prepare solution of 1ppm from 1000 ppm solution?
Make a 1 to 100 dilution of the original 1000 ppm solution. That is take 1 ml and dilute to 100 ml, or take 10 ml and dilute to 1000 ml. This will give you a 10 ppm solution.

Mix 100 mL of a 1 N solution with 900 mL of distilled water.
How do you prepare 30 percent sucrose solution?
See the two Related Questions to the left for the answer.The first is how to prepare a solution starting with a solid substance (and dissolving it). The second question is how to prepare a solution by diluting another solution.
How will prepare 200ml of 10 percent NaOH Solution?
Dissolve 0.4 g of NaOH in 100 ml of water. Try it out. Actually it is not suitable to prepare NaOH solutions in standard flasks.It should be made in beakers & must be standardised..This is done to find the correct normality...

How do you prepare 5mg percent working uric acid standard solution from stock uric acid standard solution?
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.
