How do you find adulteration in oil?
Heat small amount of vegetable ghee with acetic anhydride. Droplets of oil floating on the surface of unused acetic anhydride indicates the presence of wax or hydrocarbons. (ii) Adulteration of dyes in fat Heat 1mL of fat with a mixture of 1mL of conc. sulphuric acid and 4mL of acetic acid. Appearance of pink or red colour indicates presence of dye in fat. (iii) Adulteration of argemone oil in edible oils To small amount of oil in a test-tube, add few drops of conc. HNO3 and shake. Appearance of red colour in the acid layer indicates presence of argemone oil.
How does the presence of acetic acid affect the solubility of salt in a solution?
The presence of acetic acid can decrease the solubility of salt in a solution. Acetic acid can react with the salt, forming a less soluble compound and reducing the amount of salt that can dissolve in the solution.
How do you prepare a solution that is 5000 PPM acetic acid?
To prepare a 5000 PPM (parts per million) acetic acid solution, you would need to dissolve a specific amount of acetic acid (in grams) in a known volume of water (in liters). The formula to calculate the amount of acetic acid needed is: Mass of acetic acid (g) = volume of solution (L) x desired concentration (PPM) / 1000000.
What is the effect of adding water to the concentration of acetic acid in vinegar?
Adding water to vinegar will dilute the concentration of acetic acid in the solution. This is because the total volume of the solution increases while the amount of acetic acid remains the same. The overall concentration of acetic acid in the vinegar will decrease as a result.
Is acetic acid an electrolyte of non electrolyte?
acetic acid is a an electrolyte becase in its aqueous form it can conduct electricity i dont believe anything can be an electrolyte of a non electrolyte
What percent salicylic acid in aspirin?
37.16% is the expected yield in the reaction of salicylic acid and acetic anhydride used to form aspirin.
Aspirin is made by the reaction of salicylic acid with acetic an hydride what is the theoretical yield of aspirin if 85.0 grams of salicylic acid is treated with excess acetic an hydride?
Since salicylic acid is being reacted with excess acetic anhydride, salicylic acid is the limiting reactant of the reaction. The balanced equation of the reaction of salicylic acid and acetic anhydride indicates that their is a 1:1:1:1 ratio between every reactant and product. Based on this, it can be concluded that the moles of salicylic acid, if reacted entirely, will yield an equivalent amount of moles of aspirin. To find the theoretical yield, you must know the molecular weight of aspirin and salicylic acid. First, the amount of moles of salicylic acid must be calculated by dividing the gram amount of salicylic acid, which is 85 grams, and dividing it by its molecular weight, which is 138.12 grams per mole.85.0/138.12= 0.615 moles of salicylic acidThis is the mole amount of salicylic acid as well as the theoretical mole amount of aspirin. To convert the mole amount of aspirin into grams, this figure be multiplied by the molecular weight of aspirin, which is 180.15980.615 x 180.1598 = 111 grams of aspirin (when rounded to 3 significant figures)
What is an acetimeter?
An acetimeter is an instrument used to estimate the amount of acetic acid in vinegar.

H2SO4 in aspirin?
Yes. ^ Well to improve on this, in simple terms. A catalyst is something that brings on the reaction, in this case the liquid catalyst can only contain a little amount of water otherwise side reactions will occur and this would impact (reduce) the yield of aspirin - not good, sulfuric acid is usually used because it is 98% pure, phosphoric acid can also be used but it is only about 85% pure, still OK. HCL in its most concentrated form is only 37% pure and there fore no good at all. In a shorter to the point answer, H2SO4 is a pure catalyst which will give you a close to accurate yield of aspirin.
How do you dilute acetic acid by volume?
It can be diluted by adding the appropriate amount of water to the solution.

Can Acetic Acid be fatal if swallowed?
Absolutely. Acetic acid is an extremely corrosive substance and swallowing it is hazardous. Swallowing as little as one millimeter of acetic acid is enough to perforate the esophagus, causing death if untreated.
Which reagent is limiting cyclopentadiene or maleic anhydride?
To determine the limiting reagent, calculate the moles of each reactant using their respective masses and molar masses. Compare the moles of each reactant to the stoichiometry of the reaction. The reagent that produces the least amount of product based on stoichiometry is the limiting reagent.
