chem 110 experiment 12 tritation vinegar
need help fast please!!!
The density of vinegar is 1.01 g/mL. How would this information affect your experimental results.
2. Weak acids, such as acetic acid, typically have an odor, whereas
strong acids often do not. Explain this is so

I need it right now, please help me?? PROCEDURE PART I: DILUTING THE VINEGAR SOLUTION The vinegar solution must be diluted by a factor of 5 to be suitable for titration. 1. Obtain - 20 ml of the stock vinegar solution from the fume hood. 2. Using the 10-ml. pipet, pipet" 10 mL of the stock solution to a 50-ml volumetric flask. 3. Fill the volumetric flask to the calibration line with distilled water. Be sure not to go over...
For vinegar titration in this experiment, would the following errors cause the % acetic acid in vinegar determined to be (A) too large, (B) too small, (C) no effect, or (D) not enough information to answer. Assume that the mistake given is the only mistake made in the experiment. EXPLAIN. 1.) The burst is rinsed with distilled water, but not NaOH solution before the vinegar sample is titrated. 2.) After standardization, the NaOH solution is not stoppered and obsorbs CO2...

Calculate the moles of acetic acid, molarity of the vinegar solution, and mass %. of acetic acid in the vinegar using the average of three good trials used to titrate 5.00 mL of the vinegar. You may assume that the density of your vinegar sample is 1.01 g mL^-1. Drain off unused NaOH solution into a clean container and place it into a designated container. Wash the buret two times with regular tap water, then rinse with deionized water, and...
The table filled is the lab run. Please can you use the three informations provided above to answer the empty table Take Density of vinegar = 1.005g/mol concentration of NaOH = 0.1205M Experiment #7. Titration of Vinegar Goals 1. To determine the mass percent of acetic acid in a solution via titration. 2. To master the technique of titration. Introduction Vinegar is a common household item that is found in a number of products from salad dressing to cleaners. Vinegar...
Prelab Activity: Titrations Continued – Titration of Household Products A 2.40 g sample of vinegar was added to an Erlenmeyer flask along with 100 mL of deionized water and 3 drops of phenolphthalein indicator. It took 22.15 mL of 0.0981 M NaOH (aq) to reach the faint pink endpoint. The following balanced chemical equation represents the chemistry of the titration: NaOH (aq) + CH3COOH (aq) à CH3COO–Na+ (aq) + H2O (l) Calculate the mass % of acetic acid (CH3COOH) in...
