ʻO ka ʻakika Phosphoric kahi pūhui inorganic me ke ʻano kemika H3PO4. ʻIke ʻia ʻo ia he mau kala kala ʻole, ʻalohilohi a hiki ke hoʻoheheʻe ʻia i ka wai. He ʻakika ka waikawa Phosphoric a hiki ke hana me nā metala e hana i ke kinoea hydrogen, a me ka hana ʻana me nā waiʻona e hana i nā esters phosphate.
Hoʻohana nui ʻia ka waikawa Phosphoric i nā ʻoihana like ʻole, me ke ʻano he mea maka no ka hana ʻana i nā mea kanu, nā mea hoʻomaʻemaʻe, a me nā mea hoʻohui meaʻai. Hoʻohana ʻia ia i ka hana ʻana i nā paʻakai phosphate, nā lāʻau lapaʻau, a me nā hana kemika. I ka biochemistry, ʻo ka waikawa phosphoric kahi mea nui o nā cell, e komo ana i ka metabolism ikehu a me ka synthesis DNA, ma waena o nā kaʻina hana ʻē aʻe.
ʻO ka hana ʻana o ka waikawa phosphoric maʻamau e pili ana i nā kaʻina wai a maloʻo. ʻO ke kaʻina hana maʻemaʻe e pili ana i ka hoʻomehana ʻana i ka pōhaku phosphate (e like me ka apatite a i ʻole phosphorite) me ka sulfuric acid e hana i ka phosphoric acid, ʻoiai ke kaʻina maloʻo e pili ana i ka calcination o ka pōhaku phosphate i ukali ʻia e ka ʻohi pulu a me ka hopena me ka sulfuric acid.
I ka hana ʻana a me ka hoʻohana ʻana, hiki i ka phosphoric acid kekahi mau pilikia palekana. ʻO ka waika phosphoric paʻa kiʻekiʻe he mea ʻino loa ia a hiki ke hōʻeha i ka ʻili a me ka ʻōpū hanu. No laila, pono e mālama ʻia nā hana pale kūpono e pale aku i ka pili ʻana o ka ʻili a me ka inhalation o kona mau mahu i ka wā e lawelawe ai i ka waikawa phosphoric. Eia kekahi, hiki i ka phosphoric acid ke hoʻopilikia i ke kaiapuni, no ka mea, hiki i ka hoʻokuʻu nui ʻana ke alakaʻi i ka wai a me ka lepo. No laila, ʻo ka hoʻomalu koʻikoʻi a me nā hana hoʻolei ʻōpala kūpono i ka wā o ka hana ʻana a me ka hoʻohana ʻana.
