Al 3+ is dominant in strongly ,acidic, environments with a pH ,less, than about 5.0; AlOH 2+ and Al(OH) 2 + are important under ,less acidic, conditions of pH 4.5–5.5; Al(OH) 3 from pH 5.2–9.0; and AlOH 4 – in alkaline environments with pH greater than 8.5. Aluminum toxicity is a common problem for organisms that live in highly ,acidic, or alkaline environments.
