What is the error in the iodination of acetone experiment?
The main source of error in the lab came from not correctly measuring out the substances, resulting in a very askew time and rate of reaction.
How will you be measuring the rate of the iodination of acetone?
In this lab, rate is best described by: rate = [I2]/(average time in seconds) (see first page of lab) Find the rate for each reaction by using the calculated iodine concentration then dividing by the average time for that trial (Part Three, section a, above).
What is the order of reaction in the study of rate of acid catalyzed iodination of acetone?
The iodination of acetone is also catalyzed by hydrogen ions. The effects of varying the concentrations of acetone, iodine and hydrogen ions have been studied earlier and it has been found that the reaction is zero order with respect to iodine.
What is the purpose of iodination of acetone?
Purpose: The purpose of this reaction is to determine the orders for the reactants, the rate expression, and the rate constant for the reaction between iodine and acetone.
What is the electrophile in the iodination of benzene?
In the reaction of iodination, the iodine is reacted with the nitric acid (oxidizing agent) to get the electrophilic iodine. In the sequence of studies, the strong reagent produced by using the mixture of iodine and potassium iodide which is dissolved in the concentrated sulfuric acid is used.
Why is sodium acetate basic?
Since this reaction produces OH- ions, the sodium acetate solution is basic. Since this reaction liberates hydronium ion, the solution is acidic. Salts derived from a strong acid and a strong base give neutral solutions. Salts derived from a weak base and a weak acid may be acidic or basic.
What goitre means?
A goitre (sometimes spelled “goiter”) is a swelling of the thyroid gland that causes a lump in the front of the neck. The lump will move up and down when you swallow.
What is the strongest acid and base?
HCl: hydrochloric acid
What are some common household acids and bases?
– Coca-cola/ soft-drinks – Toilet bowl cleaners – Lemon juice (or anything citric like oranges etc.) – Shampoo – Aspirin – Phenol – Milk – Some vegetables like Spinach
How to interpret titration curves?
– Titrant: solution of a known concentration, which is added to another solution whose concentration has to be determined. – Titrand or analyte: the solution whose concentration has to be determined. – Equivalence point: point in titration at which the amount of titrant added is just enough to completely neutralize the analyte solution.
How to standardize a base?
Weight exactly about 1.4-1.6 g of dried potassium hydrogen phthalate KHP into 250 mL Erlenmeyer flask.
