ʻEriochrome uliuli ʻeleʻele R CAS:2538-85-4

ʻO Eriochrome Blue Black R kahi hui kemika i hoʻohana pinepine ʻia ma ke ʻano he anakahi i nā titrations complexometric. He uliuli a ʻeleʻele paʻa ia a hoʻololi i ke kala ma muli o ka pH o ka hopena. I kona ʻano waikawa, ʻike ʻia he uliuli, ʻoiai i kona ʻano alkaline, huli ia i poni a poni paha. ʻO kēia hoʻololi kala e lilo ia i mea pono no ka hoʻoholo ʻana i ka hopena o nā titrations e pili ana i nā ion metala, ʻoiai ka hoʻoholo ʻana i ka paʻakikī o ka wai. Hoʻohana pū ʻia ʻo Eriochrome Blue Black R i ka nānā ʻana i nā laʻana lepo a me ka wai no ka ʻike metala.
