A 25.0-mL sample of asolution of an unknown compound is titrated with a 0.115 M NaOHsolution. The titration curve above was obtained. Theunknown compound is .
NOTE: the curve has "mL of 0.115M NaOHadded to flask" (ranging from 0-45 mL in increments of 5 mL) alongx-axis, and "pH of solution in flask" (ranging from 2-12.0 inincrements of 2) along the y-axis. It shows one equivalencepoint at 25mL along the x-axis and between a pH of 7 and 8 alongthe y-axis. The curve looks like it is for a monoproticsubstance, and is in the shape of a very lazy "S" or snake.
a. a strong acid
b. a strong base
c. a weak acid
d. a weak base
e. neither an acid nor abase

Both josef loschmidt and amedeo avogadro contributed to our understanding of basic molecular numbers, sizes, and reaction ratios. neither scientist discovered “avogadro’s number” in the form we use it today (6.02 x 10 23). still, there’s a controversy over the name. research the contributions from these two scientists and read about how avogadro’s number got its name. briefly state what you think this number should be called, providing key details of each scientist’s contributions to this concept and a solid rationale for your case in naming the number.
