I came across an experiment. Does anti foam effect your pH and growth of a bioreactor ?

Most anti foams do not affect the pH in a bioreactor, at least I have not yet encountered one. However, the pH of the bioreactor will affect the efficacy of the anti foam. Anti foams that work well at pH 4.5 generally do not work well at pH 7 and vice versa. The composition of the medium may also determine which anti foam will work best for your process.

Why doesn't chromium 2+ ion use all its d-orbitals to receive lone pairs from six waters in [Cr(H20)6)]3+?

I'm guessing it's because the ligand experiences too much electron repulsion or proton repulsion from the chromium to insert them close to the 3d-orbitals which are close to the metal nucleus. Is...
