At what point during an Acids and Bases titration is/does:
a) moles of titrant added = moles of analyte originally present
b) moles of titrant added =1/2 moles of analyte originally present
c) moles of conjugate acid = moles of conjugate base
d) indicator change color
e) pH=pKa
f) pH calculated using a RICE problem where the conjugate is in water and the conjugate's K value is calculated using
Ka x Kb =Kw
g) An indicator will change color at the pKa of the---------------------????-------------------------
If the acid- base are reacting in 1:1 ratio
a) moles of titrant added = moles of analyte originally present - equivalence point when all analyte is neutralized by the titrant.
b) moles of titrant added =1/2 moles of analyte originally present- Half equivalence point when half of the analyte is neutralized by the titrant.
d) indicator change color - at the end point when one extra drop of the titrant is added to see the color change of the indicator.
e) pH=pKa - Half equivalence point when half of the analyte is neutralized by the titrant.
f)pH calculated using a RICE problem where the conjugate is in water and the conjugate's K value is calculated using Ka x Kb =Kw- at equivalence poin where the pH is controlled by the conjugates.
g) An indicator will change color at the pKa of the---------------------????-------------------------
Indicators are weak acids (HIn)and have different colors in protonated (HIn)and deprotonated form(In-)
To convert HIn in its deprotonated form pH must be greater than pKa value of the indicator.
