Step 1: Understanding the Concept:
To answer this, we must determine the chemical formula and draw the Lewis structure of thiosulfuric acid.
The prefix "thio-" indicates the replacement of an oxygen atom in an acid with a sulfur atom.
Step 2: Key Formula or Approach:
The approach is to deduce the Lewis structure of thiosulfuric acid (\(\text{H}_2\text{S}_2\text{O}_3\)) by replacing one double-bonded oxygen atom in sulfuric acid (\(\text{H}_2\text{SO}_4\)) with a sulfur atom, then count the bond types.
Step 3: Detailed Explanation:
The structure of sulfuric acid is \(\text{H}_2\text{SO}_4\).
Its structure features a central sulfur atom bonded to two oxygen atoms via double bonds (\(\text{S}=\text{O}\)) and to two hydroxyl groups via single bonds (\(\text{S}-\text{OH}\)).
To form thiosulfuric acid, we replace one of the double-bonded oxygen atoms (\(=\text{O}\)) with a sulfur atom (\(=\text{S}\)).
The molecular formula of thiosulfuric acid becomes \(\text{H}_2\text{S}_2\text{O}_3\).
In its structure, there is one central sulfur atom.
This central sulfur atom is bonded to a terminal sulfur atom via a double bond (\(\text{S}=\text{S}\)).
It is also bonded to one oxygen atom via a double bond (\(\text{S}=\text{O}\)).
Finally, it is bonded to two hydroxyl (\(-\text{OH}\)) groups via single bonds (\(\text{S}-\text{O}\)).
The question asks specifically for the types of bonds formed by the central sulphur with oxygen.
Looking at the structure, the central sulfur has:
1. One \(\text{S}=\text{O}\) double bond.
2. Two \(\text{S}-\text{O}\) single bonds (connecting to the hydrogens).
Therefore, there is one double bond and two single bonds between sulfur and oxygen.
Step 4: Final Answer:
The bonds formed with oxygen are one double bond and two single bonds.
