1.) In the titration of 25.0 mL of formic acid, HCO2H (Ka = 1.8
x 10-4) with NaOH solution. What indicator would be best to detect
the equivalence point?
a) Methyl orange (pH range: 3.1-4.4)
b) Phenolphthalein (pH range: 8.3-10.0)
c) Bromophenol blue (pH range: 3.0-4.6)
d) bromothymol blue (pH range: 6.0-7.6)
SHOW WORK PLEASE!
