Enter the tree image: bottle sizes Room temperature water 25 ml hot water and fill 75ml 100C acid HCl 10 ml quantities 6N concentration into a full 90 minute time ............................. time and then remove it from the hot and cold, adjust pH with 0.1 N NaOH, NaOH 10N, 6N HCl and 0.1 N HCl to pH neutral 250 ml size bottles, using the volume adjustment adjust the volume filter with paper 90mm 5A release p1, m1, m2 soluble substances and p2 the test tubes 0.5 ml per insert divider and a sample solution tube 2 1ml s1 prepare glucose concentration solution 0.2% w/v (0.2114g/100ml), the Trial Division had entered quantity 0.4 ml 0.2 ml, 0ml,, 0.8ml, and 1ml example 2 additional tubes per acetic acid buffer solution-a si te rothai all tubes. Until there is total quantity equals 3 ml 2 ml per tube filled DNS to provide heat, 10 minutes to cool. Water tubes each analyzed 15ml using a spectrophotometer 540 nm from aqueous solution by glucose concentration or concentration, and is followed by an example solution, m1.M2, p1, p 2 and s 1 After each example should clear distilled water before filling.

Bottle is pink and joints. Add water, room temperature 100C 75ml and 25ml water concentration 6N HCl acid into a volume of 10 ml ............................. 90 minutes after the time they took out of the air cooled pH adjusted using 10N NaOH, 0.1N NaOH, 6N HCl and 0.1N HCl until neutral pH in 250 ml volumetric flasks are used to adjust the amount of paper 5A 90mm filter with the solution. m1, m2, p1 and p2 is derived by dividing the test tube and the solution s1 1ml 0.5ml tubes, prepare a solution of Example 2 glucose concentration 0.2% w / v (0.2114g/100ml) into the test tube volume 0ml, 0.2ml. , 0.4ml, 0.8ml and 1ml each 2 tubes filled buffer solution of acetic acid - acetate citrate for all tubes. Until a total volume of 3 ml DNS filling tube 2 ml to 10 minutes to heat the water cooling tubes were analyzed using a 15ml. spectrophotometer wavelength from 540 nm to less concentrated solution of glucose concentration. Followed by a solution m1, m2, p1, p2 and s1. After each sample should be washed with distilled water before adding the new instance.

Put the bottle shaped apple at joints size, add water and hot water at room temperature 25ml 100C 75ml acid concentration 6N HCl quantity 10 ml imported............ time 90 minutes. At the end of the time and removed from the machine, cooling, adjust the pH using 10N NaOH 0.1N NaOH,,6N HCl and 0.1N HCl until pH neutral use a bottle to adjust volume and size 250 ml volume of filter paper type 5A 90mm the solvent M1 M2 P1,,, And P2 was divided into a test tube. 0.5ml and solution S1 1ml examples it 2 tube solution prepared glucose concentration 0.2% w / v. (0.2114g / 100ml) divided into a test tube of 0ml 0.2ml 0.4ml 0,,,.8ml 1ml 2 and each tube. Fill the buffer solution of acetic acid - acetate เตรต all the tube until the total quantity of 3 ml fill DNS หลอดละ 2 ml it was heated 10 minutes. The cold water tube, each 15ml analyzed using machine spectrophotometer.540 nm start from solution glucose concentrations less concentration. And the sample solution, M1M2 P1 P2 S1,, and. After each sample should be washed with distilled before, then add the new samples
