Question
The best indicator for detection of end point in titration of a weak acid and a strong base is :
Options
A.methyl orange (3 to 4)
B.methyl red (5 to 6)
C.bromothymol blue (6 to 7.5)
D.phenolpthalein (8 to 9.6)
Solution
When base is strong at end point pH changes immediately and for such titrations phrnolphthalein is good indicator .
