T9008 BOD Pono Wai Ma ka Laina Makana Aunoa
Kumu Huahana:
Wailaʻana, ʻO ka hopena o ka hoʻoheheʻe ʻana o ka potassium dichromate, ka solution silver sulfate (ʻo ke kālā sulfate ma ke ʻano he catalyst e hui pū ai hiki ke ʻoi aku ka maikaʻi o ke kaulahao momona momona o ka oxide) a me ka hui ʻana o ka sulfuric acid i wela i 175 ℃, ka hopena dichromate ion oxide o nā mea organik ma hope o ka hoʻololi ʻana o ka waihoʻoluʻu.
Nā ʻāpana ʻenehana:
