Answer:
Answers provided for the reactions with explanations in parenthesis
Explanation:
We need to find the approx. equivalent pH so we can choose an indicator.
CH3COONa +strong acid HCl - methyl orange (pH will be about 4.5)
Na2CO3 base ---> strong acid HCl- phenolphthalein (pH will be 7-8) , and then methyl orange (since carbonic acid has 2 equivalence points, it needs two indicators)
Na2C2O4 HCl- methyl orange, and then methyl orange (since oxalic acid has 2 equivalence points, it needs two indicators)
NH4Cl NaOH- Phenolphthalein, since pH = 9.75 approximately
NaOH HCl-Bromothymol blue --> since pH = 7 best for a neutral indicator
