If the solid disappears or gets smaller, then it has formed a solution with the water.
Mixing sugar into water until it dissolves is an example of a solution. This is a solution because the sugar molecules are evenly distributed and dissolved in the water, resulting in a homogeneous mixture with no visible sugar particles.
You can tell that a solution contains a weak acid if it has a pH below 7 but does not completely dissociate in water. Weak acids only partially ionize in solution, resulting in fewer free hydrogen ions. This leads to a less acidic solution compared to a strong acid.
Pure water at room temperature is a neutral solution with a pH of 7. A solution of sodium chloride (table salt) in water is neutral with a pH of 7. A solution of sugar (sucrose) dissolved in water is also a neutral solution when it has a pH of 7.
Impossale to tell. Added: If the salt solution contains chloride ion (eg. from table salt, NaCl) then silver chloride will precipitate. Both sodium and nitrate ions stay unchanged in solution.Ag+aq + Cl-aq --> AgCls
Because hydrochloric acid is a clear solution and potassium is a solid white powder the observation would be: a colourless, clear solution is add to a solid white powder which formed a solution and produced orderless, colourless gas. equation: 2H+(aq) +K2CO3(s) ---> 2K+(aq)+ CO2(g)+ H2O(l) NOTE: observations are what you actually see, therefore you would not be able to tell is the colourless gas was carbon dioxide or that water was present in the solution.
A liquid-solid solution is when a liquid turns to a solid. You can tell because if you put a glass of water in the freezer, it will turn to ice (solid).
As a general rule, chemical reactions can be identified by a number of signs, including precipitation (solids floating in the liquid), effervenscance (bubbling and fizzing), heat being given off or a colour change.

Tell me what else is in the solution. Solution containing a liter of vinegar plus a tablespoon of salt--the vinegar is the solvent. Solution containing a liter of vinegar plus a thousand liters of water--the water is the solvent. (Solutes can be either solid, liquid or gas--oxygen, a gas; diethylene glycol, a liquid; and salt, a solid, all dissolve in water.)

If it is solid at room temperature but melts when heated.
Salt is the solute. Water is the solvent. Salt water is the solution. This solution is sometimes called a saline solution.
The easiest way to tell the difference is by observing weather the particle of the solid are clumping at the bottom (suspension) or dispersed evenly throughout the liquid (solution)
Remove a drop of the solution with a glass rod and see whether any solid forms when the drop cools.
Solubility is in grams per liter (or pounds per gallon, or whatever units). One experimental method is to start with a carefully measured amount of water (your solvent in this case) and add carefully measured amounts of the unknown solid (the solute) and stir often until it doesn't dissolve anymore and some of it stays in chunks (or crystals or powder) either on the top or bottom of the water (which will also tell you whether its specific gravity is greater or less than water). The number of grams you used before it stopped dissolving is the numerator of the fraction, the measured volume of water you put it in is the denominator. The reduced fraction is its solubility.
