2- He is incorrect. Neutral salts are those salts that are neither acidic nor basic.Zwitterions contain an anionic and a cationic centre in the same molecule, but are not considered to be salts. When you dissolve salt in water the sodium chloride dissociates in Na + ions and Cl-ions, which may be written as a chemical equation: NaCl(s) → Na + (aq) + Cl-(aq) Therefore, dissolving salt in water is an example of a chemical change. Dissolving salt in water and evaporation of the water are both chemical changes. The salt would be added to the person's taste. Dissolving a solid in liquid, such as table salt in water, is a physical change because only the state of the matter has changed. On the other hand, salt NaCl when dissolved in water, it will not chemical react with water per se and you can recover the salt by evaporation. 2 Write the balanced reaction for the dissolution of each salt in water, including physical states. It is a chemical change because there is a breaking of an ionic bond between the NaCl and a making of bonds through the hydration of the ions along with the fact that new species are formed. Allowing the water to evaporate will return the salt to a solid state. When you dissolve salt in water the sodium chloride dissociates in N a + ions and C l − ions, which may be written as a chemical equation:. Yes. Physical changes such as state change and dissolving are reversible, and there is no change in total mass when they happen. A chemical change involves a chemical reaction, with new substances produced as a result of the change. Salt is a household staple, used for many purposes. Types of salt. This question is bound to provoke controversy; it certainly has before. 3- He is incorrect. This solubility involved a chemical change. As always, chemical change is characterized by the formation of new substances and the making and breaking of strong chemical bonds. When salt is added, the salt dissolves. Salts can be classified in a variety of ways. Please, before you say that such dissolution is reversible, read the entirety of this old thread. Should I call this a chemical change or a physical … The dissolution of sodium chloride in water is clearly a chemical change. The way I think about it is if you can change it back (in this case, you could filter the epsom salt out, or evaporate the water, drying it) then it is a physical change. If you dissolve the salt in, say, vinegar, then it'll be a chemical change because the chlorine from the salt (NaCl) will combine with some hydrogen in the acetic acid (don't remember the formula) and you'll end up with some weak hydrochloric acid (HCl) -- the salt will have been changed chemically, not physically. Assuming that you dissolve the salt in water: physical change. Dissolving salt in water and evaporation of the water are both physical changes. Why Dissolving Salt Would Be a Chemical Change. The reappearance of salt is evidence that the change was reversible by a physical change, so it could not be a chemical change. One of the most common purposes is adding it to boiling water, especially when making pasta. The convention is to leave water out of the equation, and simply write the reactant as the solid ionic compound and the product as ions in aqueous solution. Salts that produce hydroxide ions when dissolved in water are called alkali salts.Salts that produce acidic solutions are acid salts. N a C l (s) → N a + (a q) + C l − (a q). Now as far as i am concerned dissolving salt is a chemical change, the ionic bonds between Sodium and Chlorine ions have broken and the ions are free to move around in the water. Therefore, dissolving salt in water is an example of a chemical change. Salt dissolving into water is a physical change because the chemical makeup doesn't change. There is no simple way to extract the gas back out of water. Physical changes can often be reversed.
