    A range of concentrations (1nM to 30μM) of acetylcholine (Ach) and 5-hydroxytryptamine (5-HT) was administered to organ bath containing rat ileum. Ach and 5-HT induced contractions from 3nM (Fig. 1) and 10nM (Fig. 2) onwards respectively, both generating a shallow slope at the beginning of the concentration-response curve. EC50 of Ach is 7.47 x 10-7M whereas EC50 of 5-HT is 7.97 x 10-7M. The contraction generated by Ach and 5-HT was expressed in % Emax. As shown in Fig. 1 and 2, % Emax…

    acid-base procedures are done to determine what concentration of vinegar is collected and compare that to the actual percent concentration that the manufacturer listed on the bottle. The concentration is verified by the titration because in order to determine the unknown concentration of an acid or base, the opposite of a basic standard solution has to be added in order to neutralize it. When acids and bases are put together, a reaction called acid-base neutralization occurs. An acid-base…

After the percent acid by mass is found for each vinegar, it is possible to compare which one is the most economical. In order to solve for the percent acid by mass, we titrate each vinegar with NaOH. Titrating…
