No, H3PO4 (phosphoric acid) is not a strong acid. It is classified as a weak acid.
According to homework.study.com, phosphoric acid is a tribasic acid with phosphorus in a +5 oxidation state. It is considered a weak acid because it only partially ionizes when dissolved in an aqueous solution. While it has three hydrogen atoms that can be released, they are released sequentially, not all at once, indicating a weaker acidic nature.
