Why Do Crushed Up Tablets Dissolve Faster? The crushed tablet fizzes faster than the whole tablet. That’s because it has a greater surface area to volume ratio. That means that for the same amount of antacid (one tablet), there is more surface—or exterior—to react with the water. … Small things have a greater surface area

Physical Properties Density0.7900 g/mL (6.592 lb/gal) at 20°C 0.7844 g/mL (6.546 lb/gal) at 25°C Dielectric
What Solution Did Not Dissolve? A saturated solution at a given temperature is one that will not dissolve any more solute when the solution is in contact with solid solute. The solubility of a substance at a given temperature is the amount of it required to produce a saturated solution in a given amount of
What Is DMAP Used For? Because of its basicity, DMAP is a useful nucleophilic catalyst for a variety of reactions such as esterifications with anhydrides, the Baylis-Hillman reaction, hydrosilylations, tritylation, the Steglich rearrangement, Staudinger synthesis of β-lactams and many more. What is the purpose of DMAP? DMAP is an acyl transfer reagent that reacts regioselectively
What Is A Polar Solvent Fire? Polar Solvent: In fire fighting, any flammable liquid which destroys regular foams. Polar solvents aggressively attack the bubble by mixing with the water in the bubble structure. Polar solvents require special foam agents and mix ratios. Examples: esters, ethers, alcohols, aldehydes and keytones. Is diesel fuel a polar solvent?
Why Is It Important To Mark The Solvent Level On The Chromatography Paper? It is important to mark the solvent level on the chromatography paper when you remove it from the petri dish because so the point at which the solvent stopped could be noted in case the solvent kept advancing when removed. Why was
Which Solvent Can Dissolve Most Substances? Water is called the “universal solvent” because it is capable of dissolving more substances than any other liquid. Can dissolve many substances? Water is often called a universal solvent because many substances dissolve in it. However, no one substance can dissolve every solute. A general rule in chemistry is
Why Does Food Coloring Dissolve In Water But Not Oil? Water is a polar molecule. Vegetable oil is a non-polar molecule. … The water and the food coloring are both polar molecules Why does food coloring dissolve in water? Does food coloring dissolve in water? Yes. … The solute (food coloring) is dissolved in the
What Does Alcohol Soluble Mean? Definitions of alcohol-soluble. adjective. soluble in alcohol. Synonyms: soluble. (of a substance) capable of being dissolved in some solvent (usually water) What is alcohol soluble? Because alcohols form hydrogen bonds with water, they tend to be relatively soluble in water. … Methanol, ethanol, n-propyl alcohol, isopropyl alcohol, and t-butyl alcohol
