Sodium bicarbonate, ʻano hoʻoheheʻe kemika NaHCO3, i ʻike mau ʻia ʻo ka soda baking. ʻO ke aniani keʻokeʻo keʻokeʻo, ʻoi aku kona solubility i ka wai ma mua o ka sodium carbonate. He mea hana kemika hoʻi. Hoʻomaka ka paʻakai e decompose mālie e hana i ka sodium carbonate, carbon dioxide a me ka wai ma luna o 50 ℃, a pau loa i ka decompose ma 270 ℃. ʻO ka sodium bicarbonate he paʻakai ʻakika i hana ʻia e ka neutralization o ka ʻakika ikaika a me ka ʻakika nāwaliwali, kahi alkaline nāwaliwali ke hoʻoheheʻe ʻia i ka wai. ʻO kēia hiʻohiʻona e lilo ia i mea hū i ke kaʻina hana o ka meaʻai. Noho ka sodium carbonate ma hope o ka hana ʻana o ka sodium bicarbonate, a inā hoʻohana nui ʻia, e loaʻa ka ʻono alkaline i ka huahana i hoʻopau ʻia.
