The silver is the solvent. One is rock salt, which has sodium chloride. When the saltwater flows over the surface it melts the ice on its way, creating channels, like rivers, over the surface of the ice ball. This allows for more water molecules to surround a single particle, pulling it into solution faster. Yes, pickle brine, which works like regular saltwater. Salt will always melt ice quicker than both of them. The melting rate isn't changed by the salt, so melting "wins" (2). Because salt particles make it harder for water particles to freeze back onto the ice, the ice that is in contact with dissolved salt melts faster. 11 What makes ice melt? Don't! One of the main reasons salt is more effective at melting ice is due to its chemical properties. A perfectly solid cube packed with only water molecules can maintain its low temperature longer unlike cloudy ice, which reaches room temperatures faster thanks to the air bubbles.
