Hi. Good question. The evaporation of the alcohol should actually cool the ice somewhat. Let's see what others know.

It depends on the temp. If it's below water's freezing temp, but above that of the alcohol (I know pure alcohol doesn't freeze, but other parts of alcoholoic beverages do) then the alcohol will melt the tice faster. Also, saltwater has a lower freezing point than regular water, so I guess if the alcohol's freezing point is above that of saltwater it would speed it up. If the freezing point is below that of salt water, it would make the alcohol less effective.
I think...that's mostly speculation based on my guesses about freezing points.

It should bring the freezing point of the water down the same as the most effective of the two. If alcohol is the most effective, I dont think adding salt to it would make it more effective.

if you use alcohol to melt ice it should only be done w/strict supervision....in a glass, with the goal of chilling said alcohol for consumption.

BY ADDITION ON NON - VOLATILE SOLUTES FREEZING POINT DECREASES AND SO IS MELTING POINT
SO IT WILL DEFINITELY MELT THE ICE FASTER
NOW THE QUESTION IS BY HOW MUCH
THEN
CHANGE IN ITS MELTING POINT=2 X K X m
K= cryoscopic constant , different for each substance
1.86 for ice
m= molality of solution

do not use anything but the salt you buy for melting ice as any other salt (table salt, water softner salt) will actually "eat" away at any cement it comes into contact with over time

FASTER THAN WHAT?
