I believe they place salt on ice because the salt speeds up the process to melt the ice faster therefore the ice isn't as slippery and it doesn't stay there as long.

What else can I help you with?
What materials do you need for this science fair project why is salt put on icy sidewalks?
For a science fair project on the topic of why salt is used on icy sidewalks, you would likely need salt, ice, a control group without salt, a thermometer to measure temperatures, and a surface to simulate a sidewalk. Salt is put on icy sidewalks because it lowers the freezing point of water, leading to faster melting of ice and preventing further ice formation through the process of freezing point depression.
If you put salt on ice does it freeze or get cold faster?
Putting salt on ice lowers the freezing point of water, which causes the ice to melt. This process requires energy in the form of heat, so the surroundings, including the remaining ice, will get colder as the ice melts. In this sense, the ice will not freeze faster, but the overall system will become colder.
Which will melt first an ice cube or an ice cube with salt on it and why?
Ice cube with salt. The salt disrupts the lattice formation in the ice, lowering the melting temperature. As the salt melts ice, the surface area exposed to the salt increases, further perpetuationg the reaction.
When you add salt to ice what happens to the melting point of the ice?
Adding salt to ice decreases its melting point. Adding salt to the top of ice helps melt the ice faster.
What happens when you do the salt and ice challenge?
When you put a 20 degree cold ice cube with salt it becomes colder because it turns to salt water. Now it is about -20 degrees on your skin. What you get is a form of frostbite that turns into a burn. I would say the burn will be there for about a week to ten days or maybe less.
How you can keep coke cold with ice and salt?
Put salt and ice in a bucket and then set the coke in the bucket. You can also put ice in the coke
Why ice cream seller put salt in ice?
salt causes the temp of ice water to decrease.
Should you spread salt on ice?
Only if you want the salt on the ice.
Can you use different salt for ice cream?
no,because if you put a salt in ice cream the ice cream will be tasted not nice
Why ice don't melt in table salt?
It is because when you put in table salt, actually any salt, the ice absorbs the salt's energy and that is what make the ice colder than it was.
Can you put dry ice in salt water?
Yes, you can put dry ice in salt water. It will bubble furiously and cool down the salt water.
Will add salt to ice water help keep soda cold?
Yes, it will keep the soda cold because the salt help the ice not to melt. Don't believe me check it yourself. Get an ice cube put a little salt on it and it doest melt. Or get an ice cube put some salt on it and then get a string put on top and IT WILL STICK!!!!!!!
Why will there be a hole when you put a pinch of salt on the ice?
Some of the water molecules in the ice bond with the salt to form a solution. This solution has a higher melting point than water which forms a hole in the ice adjacent to the place where the salt was put.
How is ice cream made using salt and ice?
you just put them in a blender
Why do people sprinkle salt in front of there walk way?
Salt melts ice, so it is put on the sidewalks to melt ice.
What melts ice cubes faster sugar salt or food dye?
Salt would melt the ice cube faster because if you have noticed, people put down salt to melt the ice.
How do you do the ice and salt challenge?
You take a ice cube and some salt. First pour some salt on your arm and then put the ice cube on top and let it sit there for about 45 seconds. You will feel the burn.
