Provide the following details for each reaction. Reaction with aqueous sodium hydroxide: • ionic equation • type of reaction • colour and state of the copper-containing product Reaction with concentrated hydrochloric acid: • ionic equation • type of reaction • colour and state of the copper-containing product
Chloride ions may be tested with aqueous silver nitrate, $\text{AgNO}_3\text{(aq)}$. $\text{Ag}^+\text{(aq)} + \text{Cl}^-\text{(aq)} \rightarrow \text{AgCl(s)}$ $0.303\,\text{g}$ of a sulfur chloride is fully hydrolysed by water. Every chlorine atom present in the sulfur chloride is converted into chloride ions. The solution is made up to $100.0\,\text{cm}^3$. A $25.00\,\text{cm}^3$ portion of this solution is titrated with $0.0500\,\text{mol dm}^{-3}\,\text{AgNO}_3\text{(aq)}$. The titration uses $22.40\,\text{cm}^3$ of $0.0500\,\text{mol dm}^{-3}\,\text{AgNO}_3\text{(aq)}$. Calculate the empirical formula of the sulfur chloride. Show all your working.
