Acetic acid (CH3COOH) and trifluoroacetic acid (CF3COOH) are shown by these particulate models.
Acetic acid (CH3COOH) and trifluoroacetic acid (CF3COOH) are shown by these particulate models. The K, for trifluoroacetic acid is 104times greater than acetic acid. Use the models to account for the differences in magnitude for the K, constant. The yellow atoms are fluorine, the red atoms are oxygen, the black atoms are carbon, and the white atoms are hydrogen.

To compare the acidity of two organic acid, we must the y of their conte bases. The more stable the conjugate base, the stronger the acid. To determine if the conte base is stable, we must follow the below less Negative charges are more stable on trov o LF, Br Larger atoms with negative charge more stable Negative changes preferoide one s than on more electronegative Negative changes to be placed intoms with the more character so they prefers over...

If a solution of acetic acid (K = 1.8 x 10-5) has a pH of 2.90, calculate the original (initial) concentration of acetic acid (HC,H,O) (Report your answer in 1 sig. fig. Example: .03942 would be reported as 0.04) Be sure to include a zero in front of the decimal point. QUESTION 37 5 points Save Answer The K, for benzoic acid C.H.COOH is 6.3 x 106.

1. Acetic acid (H)CO2H) has k, = 1.8 x 10- and acetate (H:C:01") has ks = 5.6 x 10-10. (a) Write balanced chemical equilibrium equations (with physical states) for acid dissociation of acetic acid and base hydrolysis of acetate ion. (b) Write K, and equilibrium constant expressions for the above reactions. (c) Use your expressions from part b to show that Kx. = 1.0 x 10-* = [H,O'][OH). 2. For each...

A buffer solution is able to maintain a constant pH when small amounts of acid or base are added to the buffer. Consider what happens when 1 mL of a 5 M solution is added or 0.005 mol of HCl are added to a 100.0 mL solution acetic acid buffer that contains 0.0100 mol of Acetic acid, HC,H,O,, and 0.0100 mol of sodium acetate, NaC,H,O,. The initial concentration of both the acid and the base are 0.0100 mol/ 0.1000 L...

just need (e) to (h)
5. Molecules with an-OH group directly bonded to a C-C sp hybridized carbon are called "enol"'s. The types of chemical reactions which enols undergo are substantially different from those of normal alcohols. By considering the Brensted-Lowry and Lewis acid/base reactivity of an enol, you can predict a few of these differences. (a) Ethenol, the simplest "enol", can react as a BL. base in three different places, by gaining a proton at either of the two...

Review Constants Periodic Tab Part A The gas-phase reaction of NO with F to form NOF and has an activation energy of E. = 6.30 kJ/mol and a frequency factor of A = 600-108 M. The reaction is believed to be bimolecular NO(s)+F2(g) NOF(g) + F(g) where NO is a free radical. Free radicals, species with an odd number of unbound electrons tend to be more reactive. This is one reason by NO reacts so readily with gases such as...
