why does salt not dissolve in vinegar

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 a chemical change. Knowing this, we need to consider things at a molecular level. Why did the unrinsed pennies turn blue-green? When egg shell reacts with vinegar the calcium carbonate reacts with acetic acid to form carbon-di-oxide. I've tried the oil without the salt, and it definitely tastes better with a little salt. vinegar is part water, so it makes sense that salt would still dissolve in it.

When vinegar and baking soda are first mixed together, hydrogen ions in the vinegar react with the sodium and bicarbonate ions in … Vinegar is most commonly used in cooking to season fried potato chips and French fries. Vinegar has a chemical substance called acetic acid (about three percent of vinegar). How did the nail and the screw get coated with copper? The salt would ionize and break up into Na+ and Cl- ions in the water, but other than that, there wouldn't be any positive or negative effects as it does not interfere with the chemical reaction between the iron (rust) and acetic acid (vinegar). Explain why ionic substances dissolve in water.Like an explanation why they dissolve in water and what causes it to dissolve in water like the chemical reactions involved. But, moreover, vinegar can dissolve the brown oxide that is present on most older pennies, leaving a bright surface on the penny. b. vinegar is a pure substance, but oil is already a mixture. Students will have had some experiences with solids dissolving in liquid, e.g. since oil is a hydrocarbon it has only weak van der waal's forces. Calcium carbonate is rock.Rock doesn't dissolve in water--and a good thing, too! The term hydrophobic literally means... See full answer below. A vinegar molecule is many times bigger than a water molecule, and because I'm assuming the temperature is above absolute zero, the slishing and sloshing about of molecules agitates the salt molecules, causing them to dissolve faster. The rest is some more minerals and some protein. c. vinegar is polar like water, but oil is nonpolar. As the vinegar soaks into the weeds, it will draw moisture out of the leaves.
