Na2CO3+Ca(OH)2→CaCO3+2NaOH
2Na+CO3+Ca(OH)2→CaCO3+2Na+2OH
CO3+Ca(OH)2→CaCO3+2OH
CuSO4 + 2NaOH=Cu(OH)2 + Na2SO4 Cu+ SO4+ 2Na +2OH = Cu(OH)2 + 2Na + SO4 Cu+ 2OH = Cu(OH)2
Na2CO3+Ca(OH)2→CaCO3+2NaOH
2Na+CO3+Ca(OH)2→CaCO3+2Na+2OH
CO3+Ca(OH)2→CaCO3+2OH
CuSO4 + 2NaOH=Cu(OH)2 + Na2SO4
Cu+ SO4+ 2Na +2OH = Cu(OH)2 + 2Na + SO4
Cu+ 2OH = Cu(OH)2
