WebSep 8, 2015 · Aluminum makes a thick, porous oxide layer which doesn't seem to be too visible on its own, except when it's really thick and becomes a dull grey. This is commonly used in anodization to make hard protective aluminum surfaces. Aluminum oxide anodization can be readily dyed, printed etc. and is technically very useful. WebBecause of its nature as a cation (Al 3+ ), the amount of dissolved aluminum is 1000 times greater at pH 4.5 than at 5.5, and 1000 times greater at 3.5 than at 4.5. For this reason, some crops may seem to do very well, but then fail completely with just a small change in soil pH.
