What is caffeine?
Caffeine is a chemical that stimulates the central nervous system.
First, calculate the pOH
Y = 0.0096 M
[tex]\rm pOH = -log (OH)^-\\\\\rm pOH = -log (Y)^-\\\\\rm pOH = -log (0.0096)^-[/tex]
pOH =
pH = 14- pOH
14 - 2.02 = 11.98.
Thus, the pH of the solution ranges between 11 - 12. option e.
