Question about ice shot and curse on hit

I am trying to ice shot + curse on hit + curse to apply curse and chill anemies. Since I am shooting with the Reach of the council. The shot will automatically have 5 projectiles. My question is do the explosions from the ice shot apply the curse? This is quite important, since I am applying 2 curses, and definitely don’t want to use a 5L on the curse set up.
