using the properties of sodium cyanide , deduce the type of bonding that holds this compound together, explaining how you arrived at your conclusions.
write a balances equation for the reaction that occurs when sodium cyanide dissolves in water.
Any help please.
OK, consider the properties: melting and boiling points, stability of the chemical.
The reaction with water produces HCN
To determine the type of bonding that holds sodium cyanide (NaCN) together, we can analyze its properties. Sodium cyanide is a solid at room temperature and has a relatively high melting and boiling point. Additionally, it is highly soluble in water and chemically stable.
Based on these properties, we can deduce that sodium cyanide possesses ionic bonding. Ionic compounds typically have high melting and boiling points due to the strong electrostatic forces of attraction between the positively charged metal cation (in this case, Na+) and the negatively charged non-metal anion (in this case, CN-). Furthermore, the high solubility in water suggests the presence of ions that can readily dissociate in a polar solvent.
Now, let's write the balanced equation for the reaction that occurs when sodium cyanide dissolves in water:
NaCN + H2O → Na+ + CN- + H2O
In this equation, sodium cyanide dissociates into individual ions (Na+ and CN-) when it comes into contact with water. The resulting solution contains the sodium ion (Na+), the cyanide ion (CN-), and water (H2O). Please note that the cyanide ion (CN-) can react further to produce hydrogen cyanide gas (HCN):
CN- + H2O → HCN + OH-
So the overall reaction can be represented as:
NaCN + H2O → Na+ + CN- + H2O
CN- + H2O → HCN + OH-
I hope this explanation helps you understand the type of bonding and the balanced equation for the dissolution of sodium cyanide in water.
