Using the data from questions 3 and 4, calculate the experimental value of K, for this unknown acid using an ICE table.
Transcribed Image Text:Using the data from questions 3 and 4, calculate the experimental value of K, for this unknown acid using an ICE table.
Given: V of unknown acid = 0.25L V of 0.1M NAOH = 0.105L HA (ag) + NaOH (ag) -> NaA (aq) + H20) meaning its a 1:1 reaction Vi*Sı = V2*S2 can be used Cunknown acid = (0.105L x 0.1mol/L) / (0.25L) = 0.042mol/L initial acid concentration is 0.042mol/L Calculate the initial [H,O'] in mol/L in the weak acid sample using the initial pH measurement.
