Out of the following how many oxides are basic:
`TiO,Sc_2O_3,Ti_2O_3,VO,V_2O_5,CrO_3,Cr_2O_3,CuO,TiO_2`

Explanation

To determine how many of the given oxides are basic, we need to analyze the oxidation states of the transition metals in each oxide and classify them based on their acidity or basicity.

### Step 1: Identify the Oxidation States
We will identify the oxidation states of the metals in each oxide:

1. **TiO**: Titanium (Ti) has an oxidation state of +2.
2. **Sc₂O₃**: Scandium (Sc) has an oxidation state of +3.
3. **Ti₂O₃**: Titanium (Ti) has an oxidation state of +3.
