An example is:<\/li>\n<\/ol>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Hydrofluoric acid (HF)<\/strong>: composed only of hydrogen and fluorine.<\/li>\n<\/ul>\n\n\n\n<p>Since <strong>hydrofluoric acid (HF)<\/strong> contains only hydrogen and fluorine and <strong>no oxygen<\/strong>, it is classified as a <strong>non-oxy acid<\/strong>. This distinguishes it clearly from the other options provided, which all contain oxygen atoms and are therefore oxy-acids.<\/p>\n\n\n\n<p>Understanding the nature of acids is essential in both chemistry and its applications. Oxy-acids typically arise from the combination of water with non-metal oxides (like SO\u2083 or NO\u2082), forming acids with distinct polyatomic anions such as sulfate (SO\u2084\u00b2\u207b) and nitrate (NO\u2083\u207b). These acids often have multiple ionizable hydrogens and are strong electrolytes.<\/p>\n\n\n\n<p>In contrast, hydrofluoric acid, despite being a weak acid in aqueous solution, is extremely dangerous due to its ability to penetrate tissues and bind calcium and magnesium in the body. Its non-oxy nature makes its chemical behavior quite different from sulfuric, nitric, or phosphoric acids.<\/p>\n\n\n\n<p>In summary, <strong>HF is a non-oxy acid<\/strong>, while the other options are all oxy-acids because they contain oxygen as part of their structure.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Which is a non oxy-acid?A sulfuric acidB. nitric acidC. hydrofluoric acidD. phosphoric acid The correct answer and explanation is : The correct answer is: C.
