He katote ka hua ake i te memeha o te hauhā (CO2) ki rō wai. He momo pāhare ka hua ake i te hononga o te pākawa waro me tētahi atu matū (he konganuku i te nuinga o te wā), pērā i te konutai pākawa waro (Na2CO3) me te konurehu pākawa waro (K2CO3). Ko te konupūmā pākawa waro (CaCO3) tētahi matū matua o roto i te tioka, te pākeho, te anga mātaitai me te māpara. Ina whakaranua te pākawa waro me tētahi waikawa, ka puta ko te hauhā (CO2).
An ion formed when carbon dioxide (CO2) is dissolved in water. A salt is formed by the bonding of carbonate and another chemical element (usually a metal), such as sodium carbonate (Na2CO3) and potassium carbonate (K2CO3). Calcium carbonate (CaCO3) is an important constituent of chalk, limestone, shells and marble. If a carbonate is mixed with an acid, carbon dioxide gas is given off.
pākawa (pāhare - salt, ester), (waikawa - acid) - 'ate'
waro - carbon
kāponate (kupu mino)
He aha e puta ai te hauhā ina whakaranua te pākawa waro me tētahi waikawa?
Rangahautia te whakamahinga o te pākawa waro.
Whakamahia ai te konutai pākawa waro (Na2CO3) i roto i ngā tukanga whakaputa i te kōata, te pepa me te hopi.
