1. \( 250 \mathrm{~mL} \) 'lik rnekten alnan \( 50 \mathrm{~mL} \) 'lik ksm iinde bulunan \( \mathrm{Fe}^{3+} \) miktar gravimetrik yntemle bulunmak isteniyor. Gerekli ilemlerden geirilen analit \( \left(\mathrm{Fe}^{3+} ight) \) zeltisi amonyak zeltisi ile ktrlyor. kelti szlyor, kurutuluyor ve kzdrlyor. \( \mathrm{Fe}_{2} \mathrm{O}_{3} \) eklinde tartlyor ve \( 70 \mathrm{mg} \) bulunuyor. rnekte bulunan \( \mathrm{Fe}^{3+} \) miktarn mg/250 mL olarak bulunuz. Gerekleen tm reaksiyon denklemlerini yaznz. (Fe: 56, O: \( 16 \mathrm{~g} / \mathrm{mol} \) ).
