Answer 1

Explanation:

1)Colloids are mixtures in which one or more substances are dispersed as relatively large solid particles or liquid droplets throughout a solid, liquid, or gaseous medium. The particles of a colloid remain dispersed and do not settle due to gravity, and they are often electrically charged.

2)The combination of salt and vinegar creates sodium acetate and hydrogen chloride. This chemical reaction will take an old penny and shine it like new. ... If water is introduced to the mix or the penny is left soaking in the salt/vinegar solution, it will corrode quickly and turn green.
