‌EDTA ili mu mawonekedwe a ufa woyera wa kristalo. Tsatanetsatane wa mawonekedwe a EDTA ndi awa:

Mawonekedwe: Ufa woyera wopanda fungo komanso wopanda kukoma kwa kristalo.
Kusungunuka: Sisungunuka mu mowa ndi zinthu zina zachilengedwe, koma imasungunuka m'madzi ozizira (mofulumira pang'onopang'ono), madzi otentha, sodium hydroxide, sodium carbonate ndi ammonia. Mchere wake wachitsulo cha alkali umasungunuka m'madzi, ndipo kusungunuka m'madzi ndi 0.5g/L (25℃).
Malo Osungunula: Malo osungunula ndi 240℃ (kuwola), ndipo anthu ena amakhulupirira kuti malo osungunula ndi 250℃ (kuwola).
Mwachidule, EDTA imawoneka ngati ufa woyera wa kristalo kutentha kwa chipinda ndi kupanikizika, ndipo ili ndi mphamvu zina zakuthupi ndi zamakemikolo.

Ethylenediaminetetraacetic acid (EDTA) imagwiritsidwa ntchito m'njira zosiyanasiyana, kuphatikizapo:

Chelator ya ion yachitsulo: Imatha kupanga ma complexes okhazikika okhala ndi ma ion osiyanasiyana achitsulo ndipo imagwiritsidwa ntchito mu kusanthula mankhwala ndi ma labotale kuti ichotse kusokoneza kwa ma ion achitsulo pakusanthula.
Makampani Ogulitsa Chakudya: Monga chowonjezera pa chakudya, chimalimbitsa zosakaniza zina mu chakudya ndikuletsa kuwonongeka kwa chakudya ndi kusintha kwa mtundu komwe kumachitika chifukwa cha ayoni achitsulo.
Munda wa zamankhwala: Amagwiritsidwa ntchito pochiza poizoni wa zitsulo, monga poizoni wa lead, ndipo chithandizo cha chelation chimagwiritsidwa ntchito kutulutsa ayoni achitsulo oopsa m'thupi.
Zodzoladzola: Konzani zosakaniza mu mawonekedwe odzola.
Chotsukira: Chotsani calcium, magnesium ndi ma ayoni ena m'madzi olimba kuti muwonjezere kuyeretsa.
Kusindikiza ndi kupaka utoto nsalu: Kukweza ubwino wa kupaka utoto.
Ulimi: Umagwiritsidwa ntchito pokonza nthaka ndikuwongolera kugwiritsa ntchito feteleza.
Zina: Itha kugwiritsidwanso ntchito ngati chokhazikika pakuchiza madzi ndi ma PCR reactions, ndi zina zotero.
