Water molecules are polarized (one side is positive and the other is negative), which encourages the ions in salts to separate from each other.
This is a physical change because the liver salt molecules and the water molecules haven't changed - they have just intermingled.
Water is effective at dissolving sugar due to its polar nature, but crystal meth is not very soluble in water. However, substances such as acetone or other organic solvents are more efficient at dissolving crystal meth while not dissolving sugar.
Salts are electrolytes because when dissolved in water, they dissociate into ions. These ions, such as sodium (Na+) and chloride (Cl-), can conduct electricity by carrying a charge. This property makes salts an important component in electrolyte solutions that play a vital role in various biological processes and chemical reactions.
The term "saline" just means salty. A saline solution is water with salt in it. (This is not necessarily table salt, NaCl, but can be other salts as well.)
Water samples contaminated with excess salts can be purified through techniques such as reverse osmosis, which uses a semi-permeable membrane to separate salts from water. Another method is distillation, where water is heated to create vapor, leaving salts behind, and then condensed back into liquid form. Ion exchange is also effective, where ions in the water are exchanged with ions from a resin, effectively removing excess salts. Each method varies in efficiency and suitability depending on the specific salinity and contaminants present in the sample.
Water is effective at dissolving salts because of its unique molecular structure that allows it to surround and break apart the ions in the salt, causing them to separate and dissolve in the water. This process is known as hydration and helps salts dissolve in water even though water itself is not a salt substance.
Because it is hydrophilic...."water-loving." Examples of these are sugars, salts and ions. :)
Dissolving inorganic salts in water the surface tension is increased.
dissolving
By dissolving a known amount of salts in water (for NaCl 58,44 g/L).
I cannot see how. Sodium salts are normally colorless when dissolved in pure water; baking soda is basically NaHCO3, a sodium compound. Blue is normally a color from dissolving copper salts, like CuSO4. Contamination with copper ions?
The most effective substance for dissolving PETG is acetone.

Solids that can be completely dissolved in liquid materials are typically in the form of soluble salts, sugars, or certain gases. Examples include table salt (sodium chloride) dissolving in water, sugar dissolving in coffee, and carbon dioxide dissolving in water to make carbonated drinks.
Sugar dissolving in water. Salt dissolving in water. Oil not dissolving in water. Ethanol dissolving in water. Carbon dioxide dissolving in soda.
Ionic hydrides are called salt-like as salts are ionic. They are high melting and have crystal structures typical of ionic compounds. Hydrides are not straightforward salts, salts typically dissolve in water for instance, whereas hydrides react vigorously with water rather than dissolving in it.
