Most of the water on Earth (other than in mineral hydrates) is saltwater, about 97% of it. Oceans are salt water. The other 3% is fresh water, but 67% of that fresh water is in the ice caps.
That only leaves about 1% of the total water as usable fresh water. But that is still a vast amount of water, enough to fill aquifers, streams, rivers, and lakes.
What else can I help you with?
Is salt water suspension?
A simple solution of salt in water is not a suspension; instead it is a true solution. If the salt water comes from a polluted part of the ocean, it may well be a suspension, but not because of its salt content.
Is it true people are major polluters of earths fresh water supply?
Yes, human activities such as industrial waste, agriculture runoff, and improper disposal of pollutants can significantly contribute to the pollution of Earth's fresh water supply. This pollution can impact ecosystems, human health, and water quality. Implementing sustainable practices and regulations can help mitigate this problem.
Is it true that the earths surface is covered by a continuous layer of soild rock?
No, the Earth's surface is not entirely covered by a continuous layer of solid rock. The Earth's surface is made up of various types of materials, including rock, soil, water, and vegetation. The distribution of these materials varies across different regions due to factors such as geological processes and human activities.
Why does salt water rust nails?
The corrosion of iron indicates a chemical change in the metal. Rust (hydrous oxide) is an example of this change that results when iron is exposed to water or damp air. A thin film of oxide forms on the iron; this actually protects the metal from further corrosion by slowing the rate of oxidation. Where salt is present, electrochemical corrosion occurs, and the protective oxide film does not form, thus the corrosion (buildup of rust) continues unchecked. Your iron nail will indeed rust more quickly and severely in salt water. this is a very wrong statement
What happens when you put salt on snow?
I'm not the expert on this as I live down South. But salt does nothing to snow or ice. It is only after the snow or ice melts and becomes water THEN the salt lowers the freezing point of the water(now a solution) so that it will not re-freeze. Salt could provide some traction when sprinkled on the ice just as sand would. It depends what kind of salt you are using. Ordinary Sodium Chloride sprinkled on ice will first steal energy when it dissolves, thus cooling the ice and increasing friction. Remember that ice isn't slippery at all, it is the water film on it that lubricates it. After it is dissolved however, it is true that it lowers the freezing point. I believe the most common salt for salting roads is Calcium Chloride, and this behaves a little differently. I'm no expert on this salt, but I do drive on salted roads, and it seems to get right down to business and melt the ice. Perhaps it gives off heat when it dissolves. But when salting roads it is never wise to salt snow. It is very important to clear as much of the snow as possible, because salted snow becomes a slush that is extremely slippery. == ==
Is it true that if salt water is poured through a filter the salt will be trapped on the filter?
true
Does salt water clean metals?
It is not true; salt is corrosive.
Does the salt in salt water come from whale sperm?
No, it is not true.
Is it true that 91 percent of earths surface is covered in water?
no
Is it true water is a solvent for salt?
Yes, water is a solvent for salt because it can dissolve salt crystals at the molecular level. This process involves water molecules surrounding and breaking apart the salt molecules, which allows them to mix evenly throughout the water.
Is salt water is denser than fresh water true or false?
True. Salt water is denser than fresh water because the presence of dissolved salts increases the mass of the water, making it more dense.
True or false mammals can live in salt water?
true
Is it true that evaporation leaves the salt but takes the water?
Yes, it is true.
Is it true that a human can only float when there is salt in the water?
Yes if theres enough salt in the water you can float
Is it true or false salt is a solute in seawater?
True, salt is a solute in seawater. In seawater, the primary solute is sodium chloride (table salt), which dissolves in water, contributing to the overall salinity of the ocean. Other minerals and compounds also act as solutes, but salt is the most significant.
Can frogs live in salt water?
Most frogs cannot survive in salt water because their skin is permeable to salt, which can dehydrate their bodies. Some species, like the crab-eating frog, have adapted to tolerate brackish water, but true saltwater is typically harmful to frogs.
Is salt a solute in seawater true or false and why?
Yes, salt dissolves in seawater, so it is a solute.
