Malamulo Amakono a Aganyu Otupitsa Akale
Pottasche, yomwe inalembedwanso monga potashi kapena pirasium, potassium carbonate, salt salt, ndi carbonate ya potashi, nthawi zina imapezeka m'zigawo zosakanikirana ndi maphikidwe akale a ku Germany, makamaka maphikidwe akale a ma gingerbreak ( lebkuchen ). Mukhoza kuchiwona pamodzi ndi hartshorn kapena ammonia carbonate) mu maphikidwe ena a cookie monga phokoso lomwe limapindula ndi kuwala kodabwitsa kwambiri.
Ntchito Yoyamba ya Potashi ndi Kuthamanga Kwambiri
Potashi imayamba ndi lye, yopangidwa ndi kupyolera madzi kudzera phulusa losakanizika. Kutulutsa masamba a madzi a m'madzi pambuyo pa potashi. Kawirikawiri yogwiritsiridwa ntchito ku America m'zaka za m'ma 1800 ndi 18th, potashi adawotcha zinthu zopsereza. Pearlash, potashi yoyeretsedwa, inachotsa zina mwazovuta zosuta.
Okaphika oyambirira ankaganiza kuti mankhwalawa akhoza kutsitsa yisiti ngati chotupitsa, koma chifukwa cha pambuyo pake chowawa, sikuti sanalowe m'malo mwa yisiti koma potsirizira pake amalowetsedwa ndi soda. Kuwonjezera apo, kuperewera kwa mankhwala sikugwira ntchito bwino m'ma batters omwe ali ndi chiŵerengero cha mafuta, kutulutsa soapy kukoma kosati mwadzidzidzi kuyambira potashi ndi mafuta amapanga sopo ya sopo yokometsetsa.
Ntchito za Potashi ndi Zamoto
Mchere wamchere, kapu kapena potassium carbonate (K2 CO 3 ) amachitanso ndi madzi kapena asidi monga mkaka wowawasa, madzi a zipatso, kapena molasses kuti apange carbon dioxide, yomwe imapereka mankhwala ophika.
Soda yosakaniza (sodium bicarbonate) zonse koma m'malo mwa maphikidwe amakono a katundu wa German ophika. Gwiritsani supuni ya tiyi ya supuni ya supuni ya supuni ya supuni ya tiyi ya supuni. Komabe, onani kuti kukoma kwa mankhwala otsiriza kungakhale kosiyana ndi choyambirira chokha.
Wolemba mbiri dzina lake David Walbert anafotokoza kuti mafinya amatha kukhala ndi ayoni ya potassium ndi carbonate, zomwe zimakhala carbonic acid ndi kutuluka monga carbon dioxide.
Potaziyamu kuchokera kuphulika kwake imakhala ndi hydroxide ions kuchokera kumadzimadzi othandizira, kupanga potassium hydroxide. Pofuna kuteteza sopo kapena kulawa kowawa kuchokera ku potassium hydroxide, muyenera kuwonjezera asidi kuti musamalipitse, ngakhale mutatha kuyika mphamvu yophika yakufa popanda acid.
Kafukufuku wamakono omwe amachititsa kuti apange soda ndi asidi kuti azigwiritsa ntchito mofulumira mkate ndi maphikidwe ena omwe samaphatikizapo zowonjezereka monga buttermilk, honey, kapena yogurt. Mtundu wakuphika wa ku Germany, wophika limodzi, sagwira ntchito mosiyana ndi mitundu iwiri yochita zambiri yomwe imapezeka ku United States.
