Is salt water a heterogenerous mixture?
No, Salt water is a homogenous mixture, as long as it is not over saturation point. Water dissolves salt, therefore the solution is able to be even concentration throughout.
Mix the salt-sand mixture with water and filter it. As the salt will be dissolved in the water, when it is filtered the residue will be the sand and the filtrate will be the salt-water mixture. To separate the salt-water mixture, it must go through a process called 'evaporation'. When all the water is evaporated from the salt-water mixture, everything left will be the salt.
Salt and water is a mixture. In a mixture you can mix them together then take them apart. When you put salt in water the salt does not dissolve therefore it is a mixture. If salt dissolved in water it would then be a solution,but salt does not dissolve in water so it is a mixture. Salt does dissolve in water to form a solution, which is a mixture.
