Tea room discussion
Is this really uncountable? Thryduulf 00:38, 8 August 2008 (UTC)


 * I suppose there's the 7% periodic acid in the tall jar, and the undiluted periodic acid in the flask—that's two periodic acids. I would call it a mass noun, which would indicate that it isn't normally pluralized, but not that it can't be. —Michael Z. 2008-08-08 04:15 z 


 * Not to mention the different isotope ratios. This renaming for Wiktionary purposes of the concept, apparently in closer conformity to grammarian practice, seems highly desirable. It does not eliminate the need to review all of the nouns displayed as uncountable because many of them aren't mass nouns either. DCDuring TALK 04:26, 8 August 2008 (UTC)


 * Plenty of decent google hits for periodic acids from Chemistry literature. Changed template to countable. --Jackofclubs 15:58, 19 January 2009 (UTC)
