cause everything is hard in my class so i need help. my science teacher mr worldrige is retated
You can evaporate it.
The density of a salt water solution compared against the densities of "pure" water and salt provides an approximate value of the ratio of water to salt in the mixture.
There are two types of mixtures:Homogeneous or solution; andHeterogeneousSolution is a special type of mixture which is uniform throughout for instance salt dissolved in water. So any mixture which is homogeneous in nature is a solution.Every solution is a mixture but every mixture is not a solution.
It's hard to tell. Almost all table salt sold in the US is iodized.
A compound contains 2 or more different elements chemically bonded together (you can't separate them by distillation, filtration, evaporation etc). A mixture contains two or more different substances that are not chemically bonded together.
A homogeneous mixture is of uniform content throughout the entire container. In other words, the 2 parts of the mixture are completely mixed (example: vinegar and water). A heterogeneous mixture will not be completely mixed, and the concentrations are not even throughout the mixture (example: oil and water).

Its heterogenous... heterogenous is two or more materials mixed in and you can tell they are present, homogenous is when you cannot tell they are seperate such as salt water.
i dont know please tell me someone, i know that it has been used to make ink in the olden days but what else?
You can tell if salt is salt by ingesting it. If you know what salt is, than you probably know what it tastes like
You can't tell that a mixture is a solution to anything until the mixture is thoroughly chemically tested and proven.
