FALSE

Concentration (M)= mol of substance/ given liter

OH- is hydroxide, a BASE
> proton acceptor
> produce hydroxide ions when dissolved in solution
H3O+ is hydronium, an ACID
> proton (H+) donor
> produce hydrogen ions when dissolved in solution

For more BASIC solutions:
concentration of BASE> con. of ACID
con. OH- > con. H3O+

The concentration of H3O+ must be less than or SMALLER than 1x10^-7 (so 1x10^-8, 1x10^-9 etc.) whereas the concentration of the base, OH-, must be LARGER than 1x10^-7. So there is a higher concentration of OH-, or more mol OH per L of solution.

pH measure the concentration of H+ or H3O+ ions in solution. It is -log[H+] ... so if the concentration was lower than 1x10^-7 mol/ L
-log(1x10^-8)= pH= 8 which is Basic (x>7)

Remember, for the pH scale,
(0-7)= acidic
7= neutral
(7-14)= basic

Conversely, for acidic solutions, the concentration of hydronium would increase

BARSIC [14]

Answer:

The correct appropriate will be Option 1 (Acid anhydrides are less stable than esters so the equilibrium favors the ester product.)

Explanation:

  • Acid anhydride, instead of just a carboxyl group, is typically favored for esterification. The predominant theory would be that Anhydride acid is somewhat more volatile than acid. This is favored equilibrium changes more toward the right of the whole ester structure.
  • Extremely responsive than carboxylic acid become acid anhydride as well as acyl chloride. Thus, for esterification, individuals were most favored.

The other options offered are not relevant to something like the scenario presented. So, the solution here is just the right one.
