Uguhingura ibintu bishasha, gukora neza cane no kwizigirwa ni vyo bihambaye cane mu bucuruzi bwacu. Ivyo vyiyumviro uno musi vy’inyongera kuruta uko vyari bimeze kera ni vyo bituma turoranirwa nk’ishirahamwe ry’ubunini hagati rikora ku rwego mpuzamakungu ry’Igiciro c’Ivyuma vy’Ivyuma vy’Ivyuma 92% 95% 98% 99% Ivyuma vy’Ivyuma vy’Ivyuma, Turaba imbere mu gushinga ubucuruzi butera imbere bw’abaguzi bashasha mu gihe c’imbere mu gihugu!
Uguhingura ibintu bishasha, gukora neza cane no kwizigirwa ni vyo bihambaye cane mu bucuruzi bwacu. Ivyo vyiyumviro uno musi vy’inyongera kuruta uko vyari bimeze kera ni vyo bituma turoranirwa nk’ishirahamwe ry’ubunini hagati rikora ku rwego mpuzamakungu kubera , Uburyo bwiza n’igiciro gisanzwe vyatumye turonka abakiriya bashikamye n’izina ryiza. Mu gutanga ‘Ibintu vyiza, Ibikorwa vyiza cane, Ibiciro bihuye n’ibindi n’ugushikana vuba’, ubu turindiriye mbere n’ugukorana n’abaguzi bo mu mahanga bishingiye ku nyungu rusangi. Tuzokora n’umutima wacu wose kugira ngo tunoze ibintu vyacu n’ibikorwa vyacu. Turasezerana kandi gukorana n’abafatanyabikorwa mu bucuruzi kugira ngo dushire hejuru ubufatanye bwacu no gusangira ivyo turonka. Turabahaye ikaze n’igishika cinshi kugira ngo muze gusura uruganda rwacu ata buryarya.













Igerageza ry'ibirimwo Calcium Formate
1. Incamake y'uburyo
Mu munyuro w’ivyatsi vy’ivyatsi vy’ivyatsi vy’ivyatsi vy’ivyatsi vy’ivyatsi, hashirwamwo ivyatsi vy’ivyatsi vy’ivyatsi vy’ivyatsi vy’ivyatsi vy’ivyatsi. Inyuma yo gushusha kugira ngo ivyuka bibe vyuzuye, iyo permanganate ya potassium isigaye irabohora iyode mu yodide ya potassium mu kintu gifise aside. Iyo yode irekuwe iraheza igahindurwa n’umuti w’ivyatsi bita sodium thiosulfate.
2. Uburyo bwo gupima
Ugutegura akarorero:
Pima hafi 0,4 g y’ico gipimo (kibereye gushika kuri 0,0002 g) hanyuma ugishire mu gitereko c’uburemere bwa 250 mL.
Ushiremwo amazi gushika aho ikimenyetso kigeze, hanyuma ubivange neza.
Inyishu y'uguhindura umwuka:
Pipete 25,00 mL (canke 10 mL) y’umunyu mu gitereko c’iyode.
Wongeremwo 0,2 g y’umunyu w’amazi utagira amazi hanyuma ubivange.
Wongeremwo neza na neza 50,00 mL (canke 20 mL) y’umunyu w’ivyatsi vy’ivyatsi vy’ivyatsi.
Shusha mu mazi yo kwoga iminota 30, hanyuma ushiremwo.
Ukwidegemvya kwa iyode n'ugupima:
Wongeremwo 6 mL y’umunyu w’aside sulfurique na g 2 z’iodure ya potassium.
Bibike mu mwijima iminota 5.
Titrate n’umuti w’ivyatsi vy’ivyatsi vy’ivyatsi.
Hafi y’iherezo, wongereko 3 mL y’ikimenyetso c’imitsi (0,5%).
Bandanya ukora titration gushika ibara ry’ubururu rizimangana.
Ikigeragezo c'ubusa:
Kora ikigeragezo c’ubusa mu buryo bumwe bwo gukosora.
