bilangan oksidasi Cl dalam senyawa KClO2 adalah ... a. +7 b. +3 c. +5 d. + 1 e. -1

<p>Jawaban : b. +3</p><p>&nbsp;</p><p>Bilangan oksidasi adalah bilangan yang menyatakan muatan suatu atom atau suatu ion. Tiap zat memiliki nilai bilangan oksidasinya masing-masing.</p><p>&nbsp;</p><p>Biloks unsur IA dalam suatu senyawa = +1</p><p>Biloks O dalam senyawa non peroksida = -2</p><p>&nbsp;</p><p>Biloks Cl dalam senyawa KClO₂ :</p><p>Biloks K + Biloks Cl + (Biloks O x 2) = Muatan KClO₂</p><p>&nbsp; &nbsp; +1 &nbsp; &nbsp; &nbsp; &nbsp; + Biloks Cl + (-2 x 2) &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;= 0</p><p>&nbsp; &nbsp; +1 &nbsp; &nbsp; &nbsp; &nbsp; + Biloks Cl + (-4) &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;= 0</p><p>Biloks Cl &nbsp;+ -3 &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; = 0</p><p>Biloks Cl &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;= +3</p><p>&nbsp;</p><p>Jadi, biloks Cl adalah +3</p>
