The Sweet / Sharpness Of Orange Juice Evaluated By Titration

2. To titrate a hydrochloric acid solution of “known” concentration with standardized 0.5M sodium hydroxide.

H. How would you prepare 10 mL of a 0.25M HCl solution if 1M HCl was available? How much

12. Write the balanced chemical reaction of the product of the reaction described above (problem 11) with NaOH. Is the product of this reaction soluble in aqueous solution?

The results showed the molarity of the NaOH solution. This experiment was completed twice and a new average molarity

Notice that the effective analytical connection for analysis of hypochlorite anion by the thiosulfate anion in this

After the twenty minutes elapsed, the flask was cooled to room temperature and then titrated with the remaining NaOH until the colorless solution remained pink. The final volume was then recorded. While solution #1 was heating the same process was repeated with solution#2 and the second burette

9. How many moles of NaOH would be needed to completely react with all of the excess HCl determined in problem 8?

then we know Ca2+ is involved in the solution. Next we add OH into the

ii. The second part of the titration series involves titration of NaOH with Hydrochloric acid (HCL). Again, three reps of titration and a blank titration have to be completed. A volumetric pipet is used to measure 10.00mL of HCL into three labeled conical flasks. Then the flasks are filled with deionized water until about the 50mL mark. A buret is

During a titration the pH of the solution will be monitored using a pH meter from that we get a titration curve. The titration curve is then used to determine the equivalent molecular weight and Ka value of the unknown weak acid, from that we are

The process was then repeated for the second reaction but using 1.00-mL of a 6.00-M phosphoric acid solution and 4.00-mL of a 3.00-M sodium hydroxide solution.

Thus causing sodium hydroxide dependent variable to be the volume of Hydrochloric acid used in titration. The independent variable to be the concentration of sodium hydroxide used in the experiment. The controlled variables is the volume of sodium hydroxide used in titration process. After the positive sodium ions and negative sulfide irons get dissolved into water,

4. Calculate the number of moles of NaOH used in reactions one and two. Show work here and record your answer in Data Table 2.

The pertaining research involves the electrolytes in drinks. “Electrolyte” will be defined and its description of what they do, what they are, and how they help people will be further explained. The intention is to establish the efficiency of sports drinks and orange juice and then compare them. The pros and cons of both the orange juice and sports drinks will be elucidated through the research. Other drinks consumed after exercise will also be researched and their efficiency will be explained.

Garcinia Cambogia contains hydroxyl-citric acid which is also found in oranges and lemons. Garcinia Cambogia has many health benefits which include reducing appetite, improving metabolism,
