Question

if you are titrating weak acid against a strong base which indicator will be used and why​

Answer 1

Answer:

For a strong base-weak acid titration, the equivalence point is probably near pH 9. Phenolphthalein is great for this titration. For a strong acid-weak base titration, the equivalence point is probably near pH 5. Here you could use an indicator like methyl red (pH 4.4 to 6.2).
