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 elements in each oxide and relate them to their acidic or basic character. Generally, lower oxidation states correspond to more basic oxides, while higher oxidation states correspond to more acidic oxides.

### Step-by-Step Solution:

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