Chlorine reacts at all temperature with sodium hydroxide according to the following equation :$$\ce{Cl2 + 2 NaOH -> NaCl + NaClO + H2O \tag{1}}$$ which can also be written with ions : $$\ce{Cl2 + ... • 25k 0 votes ### Why Cu(s) + 4HNO3(aq) → Cu(NO3)2(aq) + 2NO2(g) + 2H2O(l) reaction really occurs? Copper is attacked by molecular \ce{HNO3}, and neither by \ce{H+} nor by \ce{NO_3^-} ions. The equation is :$$\ce{3 Cu + 8 HNO3 -> 2 NO + 4 H2O + 3 Cu(NO3)2}$$At high \ce{HNO3} ... • 25k 0 votes ### Why Cu(s) + 4HNO3(aq) → Cu(NO3)2(aq) + 2NO2(g) + 2H2O(l) reaction really occurs? It is true that Copper has a negative oxidation potential hence H+ ion is unable to oxidise \ce{Cu(s)} to \ce{Cu+} or \ce{Cu}^{2+}. It is the reason why Copper does not react with strong mineral ... 1 vote ### What is the black sticky residue after heating copper hypophosphite? Three months later I hope you are still interested and testing. The black residue is one (if any) of the disadvantages of this method of activation.

According to the Handbook of Chemistry and Physics, sulfamic acid $\ce{NH2SO3H}$ is decomposed at about $200°$C in $\ce{NH3}$ and $\ce{SO3}$, which produces immediately ammonium bisulfate \$\ce{NH4HSO4}...
