Phosphoric acid, inozivikanwawo se orthophosphoric acid, inorganic acid inowanzoshandiswa mumaindasitiri akasiyana. Iine acidity yakasimba zvine mwero, chimiro chayo chemakemikari iH3PO4, uye huremu hwayo hwemamorekuru i97.995. Kusiyana nemamwe ma acid acids, phosphoric acid yakagadzikana uye haiputsi nyore nyore, zvichiita kuti ive sarudzo yakavimbika kune akasiyana maapplication. Kunyange zvazvo phosphoric acid isina kusimba sehydrochloric, sulfuric, kana nitric acids, yakasimba kudarika acetic uye boric acids. Uyezve, iyi asidhi ine hunhu hweasidhi uye inoshanda senge isina kusimba tribasic acid. Zvakakosha kucherechedza kuti phosphoric acid ndeye hygroscopic uye inotora unyoro kubva mumhepo. Mukuwedzera, ine simba rekushandura ku pyrophosphoric acid kana inopisa, uye kunotevera kurasikirwa kwemvura kunogona kuishandura kuita metaphosphoric acid.
