What is the melting point of ice?

The triple-point of water is a standard fixed point in modern thermometry.Why? What is wrong in taking the melting point of ice and the boiling point of water as standard fixed points (as was originally done in the Celsius scale)?

A copper block of mass 2.5 kg is heated in a furnace to a temperature of 500^2C and then placed on a large ice block. What is the maximum amount of ice that can melt? (Specific heat of copper = 0.39 J g-^1K ^-1 , heat of fusion of water = 335 J g^-1)
