albertlee Posted April 5, 2004 Share Posted April 5, 2004 Some one told me that in the ion, we always write oxygen last, although it is positive(since cation always is written first)... for eg, SO4, but why we write OH instead of HO as a compound ion? Any help> Link to comment Share on other sites More sharing options...
YT2095 Posted April 5, 2004 Share Posted April 5, 2004 SO4 is an acidic ion as is NO3, OH is an alkaline ion. as a general rule of thumb most inorganic compounds are writen in order of electronegativity from the most electro positive to the most electronegative Link to comment Share on other sites More sharing options...
