What are qualitative changes across the shock waves?

Shock waves are very thin regions in a supersonic flow across which the pressure, density, temperature, and entropy increases, the Mach number, flow velocity, and total pressure decreases, and the total enthalpy stay the same.

Why total enthalpy remains same across the normal shock wave?

The flow across a shock wave is adiabatic, and for steady, inviscid, adiabatic flow, total enthalpy constant, is a statement of the energy equation, hence the total enthalpy remains same before and after the normal shock wave.
