\(n_{Cu\left(OH\right)_2}=\dfrac{34.3}{98}=0.35\left(mol\right)\)
\(CuCl_2+2KOH\rightarrow Cu\left(OH\right)_2+2KCl\)
\(CuSO_4+2KOH\rightarrow Cu\left(OH\right)_2+K_2SO_4\)
\(n_{KOH}=2\cdot0.35=0.7\left(mol\right)\)
\(V_{dd_{KOH}}=\dfrac{0.7}{2}=0.35\left(l\right)=350\left(ml\right)\)
Gọi CTC của CuCl2 và CuSO4 là CuX
\(n_{Cu\left(OH\right)_2}=\dfrac{34,3}{98}=0,35\left(mol\right)\)
PTHH: CuX + 2KOH --> K2X + Cu(OH)2
____________0,7<-------------0,35
=> V = \(\dfrac{0,7}{2}=0,35\left(l\right)\)
