FeCl3 reacts nrog NaOH tsim Fe (OH) 3 thiab NaCl.

Hauv lwm lo lus, hlau (III) chloride reacts nrog sodium hydroxide tsim hlau (III) hydroxide thiab sodiumchloride. Qhov sib npaug sib npaug rau cov tshuaj tiv thaiv nruab nrab FeCl3 thiab NaOH yog FeCl3 + 3NaOH -> Fe(OH)3+ 3NaCl. Yog li ntawd, qhov no yog hu ua nag lossis daus tshuaj tiv thaiv.

Yog li ntawd, thaum twg FeCl3 tov ntxiv rau NaOH?

Yog FeCl3 yog ntxiv Nyob rau hauv cov dej kub dhau, lub postively them sol ntawm hydrated ferric oxide yog tsim vim adsorption ntawm Fe3+ ions. Txawm li cas los xij, thaum ferric chloride yog ntxiv rau NaOH , ib tug tsis zoo nqi sol yog tau nrog adsorption ntawm OH-ions.

Kuj Paub, qhov piv ntawm moles ntawm NaOH reacting ib mole ntawm FeCl3 yog dab tsi? Raws li rau tus tshuaj tiv thaiv 1 mole ntawm FeCl3 yuav teb nrog 3 moles of NaOH . Yog li 162.2 g FeCl3 yuav teb nrog (3 × 39.99) = 119.97 g ntawm NaOH . yog:0,739g rau ua FeCl3.

Hais txog qhov no, yuav ua li cas thaum ferric chloride reacts nrog ammonium hydroxide?

Thaum twg ammonium hydroxide yog ntxiv rau kev daws ntawm ferric chloride ces nws tshwm sim nyob rau hauv lub tsim ntawm ferric hydroxide thiab ammonium chloride . Cov tshuaj tshuaj tiv thaiv kev sib npaug rau qhov no tshuaj tiv thaiv yuav ua raws li. Qhov no tshuaj tiv thaiv yog kev hloov pauv ob zaug tshuaj tiv thaiv Raws li muaj kev sib pauv hauv ions ntawm ob qhov sib txawv.

Qhov sib npaug ntawm HCl thiab NaOH yog dab tsi?

Rau balance NaOH + HCl = NaCl + H2O koj yuav tsum nco ntsoov suav tag nrho cov atoms ntawm txhua sab ntawm tshuaj sib npaug.
