Question

Напишите диссоциацию для следующих веществ. Na2CO3, HI, BaBr2, Na3PO4, AgNO3, KOH, H2SO4, K2SiO3, AlCl3, (NH4)3PO4, HClO4, Ba(OH)2, Al2(SO4)3, H2Cr2O7.

Answer 1

$Na_{2}CO_{3}\rightarrow 2Na^{+}+CO_{3}^{2-}\\\\HI \rightleftharpoons H^{+}+I^{-}\\\\BaBr_{2}\rightarrow Ba^{2+}+2Br^{-}\\\\Na_{3}PO_{4}\rightarrow 3Na^{+}+PO_{4}^{3-}\\\\AgNO_{3}\rightarrow Ag^{+}+NO_{3}^{-}\\\\KOH\rightarrow K^{+}+OH^{-}\\\\H_{2}SO_{4} \rightleftharpoons 2H^{+}+SO_{4}^{2-}\\\\K_{2}SiO_{3} \rightarrow 2K^{+}+SiO_{3}^{2-}\\\\AlCl_{3} \rightarrow Al^{3+}+3Cl^{-}\\\\(NH_{4})_{3}PO_{4} \rightarrow 3NH_{4}^{+}+PO_{4}^{3-}\\\\HClO_{4} \rightleftharpoons H^{+}+ClO_{4}^{-}$

$Ba(OH)_{2}\rightarrow Ba^{2+}+2OH^{-}\\\\Al_{2}(SO_{4})_{3}\rightarrow 2Al^{3+}+3SO_{4}^{2-}\\\\H_{2}Cr_{2}O_{7}\rightleftharpoons 2H^{+}+Cr_{2}O_{7}^{2-}$
