C. Write a balanced equation for the neutralization of acetic acid with NaOH. HC2H302+NaOHNaC2H302+H20 D. How would your results have differed if the tip of the burette was not filled with sodiumhydroxide before the initial volume reading was recorded? It would have shown more NaOH then there actually was resulting in there
Eating ¼-cup of red-skimmed peanuts w/your meal provides the same amount of antioxidants. Rose hip powder blocks fat buildup – enjoying 1 T. of this sweet, fruity ‘n slightly tart powder (mix it into smoothies, yogurt or other food) helps block the fat storage that triggers high blood sugar ‘n insulin resistance. Rose hip powder inhibits fat formation in the liver. TIPS: if u prefer, dissolve the powder in a cup of boiling water ‘n drink it as a tea. Fish protects your heart – people who eat at least (3) three fish meals weekly have more heart-healthy HDL cholesterol levels in their blood than less frequent fish eaters.
This product is pitched as an antiseptic mouth rinse that kills germs caused by gingivitis, plaque, and bad breath and this product is also approved by the American Dental Association. Active ingredients Eucalyptol 0.092%, Menthol 0.042%, Methyl salicylate 0.060%, and Thymol 0.064% these ingredients purpose anti-gingivitis / anti-plaque. Inactive ingredients water, alcohol 21.6%, sorbitol solution, flavor, poloxamer 407, benzoic acid, sodium benzoate, FD&C green no.3. In reviewing both products Equate Blue Mint mouth rinse and Listerine Cool Mint mouth rinse we have come to the conclusion thus far they both contain the exact same ingredients proportions and all. Not too much difference.
In basic solutions, the solution will turn greenish-yellow. The color of the solution changes in response to the changes in the hydrogen ion concentration. The equation for pH is pH=-log[H+]. A pH indicator measures whether a substance, usually a liquid, is acidic or basic. When the indicator comes in contact with the substance, the indicator’s color corresponds to the substance’s approximate change.
With the use of this technique we placed chlorine, bromine, and iodine into solutions containing chloride, bromide, and iodide. In the reaction the free halogen (X2) oxidizes the other halide ion (Y-) and gets reduced by gaining electron(s). In table 3, chlorine was the strongest oxidizing agent and iodine was the weakest oxidizing agent. Since chlorine was the strongest oxidizing agent it will react more and the weak agent will react less. This explanation can be demonstrated in table 3 also because the results of the reactions demonstrates that chloride reacted more by the color of the product compared to the color of chloride in the mineral oil.
Add a liquid (e.g., water, milk) and violà. If you really must know, baking powder also contains a dry starch to absorb any moisture in the air so the desired CO2-producing reaction
How to Make Homemade Glue Out of Milk Milk contains casein, a protein that is used in the production of glues, paints and plastics, as well as some food products. If you heat up milk and add an acid, such as vinegar, you will cause a chemical reaction whereby the casein separates from the liquid component of milk. When you add a base, such as baking soda, to the casein extracted from milk, the acid is neutralized and the result is a smooth adhesive that can be used for wood and paper.

Results : Yield (mass in gram) = __________________0.128 g_____________________ Melting point of pure phenyl benzoate (OC) = ___________70O______________ Melting point of your phenyl benzoate (OC) = ___________69O______________ Questions : 1. Why do we use NaOH solution to dissolve phenol rather than water in step 1 ? Because NaOH can be use to change the phenol to ion form, which can be more soluble in the aqueous
Acids have a pH level of 1 to 6. Bases: Mustards and medicines are examples of a base. Flavor is added to medicines to offset the bitter taste. Bases have a pH level of 8 to 14. pH Scale A pH scale ranges from one to 14 and displays the range of acids and bases from top to bottom. Acids (low pH) range from one to six on the scale, while bases (high pH) range from eight to 14 on the scale.
Kobs is the slope on the graph plotting Vol of NaaS2O3 against time. Specific hydrogen ion catalysis Kobs = KH+[H+] This is used when a strong acid is being used in the reaction as it acid fully dissociated and there is no A- value. This is the equation used for reactions (i), (ii) and (iv) as they used HCl as the acid. General acid catalysis Kobs = KH+[H+] + KHA[HA]. This is used when a weak acid is being used in the reaction as it acid does not fully dissociated and there is an A- value.
