What hazards are associated with phenolphthalein and what precautions should be taken when using it?

Is phenolphthalein a carcinogen?
It is more likely that the multiple biological properties of phenolphthalein, including its ability to form free radicals, its clastogenic activity, and its estrogenic activity, contributed to the carcinogenic effects observed. These studies show that phenolphthalein is a multisite/multispecies carcinogen.
Why is oxalic acid is classified as a weak acid?
While oxalic acid or C2H2O4 has a very mere degree of ionisation of 10% so only a part of the acid gets completely ionised and the other part remains unionised. The basicity of an acid is used to classify acids on the number of replaceable H+ ions. Example: HCl is a monobasic acid while oxalic acid and sulphuric acid are dibasic acids.
Is oxalic acid harmful when swallowed?
Oxalic acid solutions are highly irritating and corrosive. Ingestion and absorption of oxalate cause acute hypocalcemia resulting from precipitation of the insoluble calcium oxalate salt. Calcium oxalate crystals may then deposit in the brain, heart, kidneys, and other sites, causing serious systemic damage.
