Pauda keʻokeʻo EDTA 4NA CAS 13235-36-4
ʻO EDTA-4Na, kahi mole liʻiliʻi liʻiliʻi i loko o nā pūʻulu amino a me ka carboxyl, hoʻohana nui ʻia i ka kemika analytical ma ke ʻano he mea paʻakikī. Loaʻa iā ia kahi ākea ākea a me nā kumukūʻai haʻahaʻa. ʻO EDTA tetrasodium ka pauka kristal keʻokeʻo. Hiki ke hoʻoheheʻe ʻia i ka wai a me ka waikawa, hiki ʻole ke hoʻoheheʻe ʻia i ka waiʻona, benzene, a me ka chloroform.
