strongly acid

When the two solutions described above are mixed, a strongly acid solution, colored a bright pink, results.

Consequently, these organic compounds do not interfere with tests which may be carried out in strongly acid solution.

Mould growth, on the other hand, is most vigourous in media that are strongly acid to phenolphthalein.

These indicate very clearly the increased susceptibility to oxidation in strongly acid solutions.

If the solution is strongly acid it should be almost neutralised by the cautious addition of dilute ammonia.
