Question

CuSO4->Cu(OH)2->CuO,CuCl2->Cu(NO3)2->Cu(OH)2->CuSO4

Answer 1

(1) \(CuSO_4+2NaOH\xrightarrow[]{}Na_2SO_4+Cu\left(OH\right)_2\downarrow\)

(2) \(Cu\left(OH\right)_2\xrightarrow[]{t^\circ}CuO+H_2O\uparrow\)

(3) \(CuO+2HCl\rightarrow CuCl_2+H_2O\)

(4) \(CuCl_2+2AgNO_3\xrightarrow[]{}Cu\left(NO_3\right)_2+2AgCl\downarrow\)

(5) \(Cu\left(NO_3\right)_2+Ca\left(OH\right)_2\xrightarrow[]{}Ca\left(NO_3\right)_3+Cu\left(OH\right)_2\downarrow\)

(6) \(Cu\left(OH\right)_2+H_2SO_4\xrightarrow[]{}CuSO_4+2H_2O\)
