It contains water, sugar, and carbon dioxide, which forms bubbles. Salt easily dissolves in water, but salt water cannot be classified as a substance because its composition can vary. Other salts like bromides and gypsum are more soluble than carbonates but still not as soluble as sodium chloride or potassium and magnesium-based salts. Latest answer posted September 19, 2015 at 9:37:47 PM. Helmenstine, Anne Marie, Ph.D. (2020, August 26). The World's Most Comprehensive Water Resource Database. 3.5: Pure Substances and Mixtures - Chemistry LibreTexts In solution, the Na+ and Cl- ions are completely dissociated from each other and form electrostatic interactions in water with hydrogen and oxygen atoms. Is sodium an heterogeneous or homogeneous mixture? - Answers Aerosol. In contrast, scientists have identified tens of millions of different compounds to date. Some mixtures that appear homogeneous at first glance are heterogeneous upon closer inspection. You also have the option to opt-out of these cookies. Wiki User 2014-06-03 20:27:26 This answer is: Study guides Chemistry 20 cards To name a monatomic anion change. Based on physical characteristics, we can classify matter into two main categories: pure substances and mixtures. This website uses cookies to improve your experience while you navigate through the website. This is why the NaCl dissolves and forms a single visible phase to the eye (a homogeneous mixture). It is only when the water has other impurities or substances in it (as in the case of seawater), has a particularly insoluble kind of salt, has a cooler temperature or has become saturated that the mixture might lean towards becoming heterogeneous. Sodium is a pure substance. Dr. Helmenstine holds a Ph.D. in biomedical sciences and is a science writer, educator, and consultant. Sodium is a chemical element, so it is a pure substance. Here's a good explanation from Compound vs Mixture - Difference and Comparison A compound contains atoms of different elements chemically combined together in a fixed ratio.
