- Example: when 52 ml pure ethanol is mixed with 48 ml of water a volume of 96.3 ml is obtained instead of 100 ml. That is why it is important to distinguish between a percentage by volume or weight. For ethanol we provide a table that allows for the most commonly used concentrations in hand rubs / gel to compare the values of both scales.
When you prepare the saturated NaCl solution, heat up the solution with an excessive amount of salt and stir thoroughly to ensure that you are starting with a saturated salt solution. The more concentrated the HCl the quicker the result. When working with strong acids, wear eye protection and a lab apron.

- Jul 07, 2010 · Alkalis (or "bases") such as NaOH and Ca(OH) 2 dissolved in water give negative hydroxyl ions OH. And finally, acids and alkalis in solution can combine vigorously, releasing heat and forming salts (such as NaCl or CaSO 4) and water. In addition, many other ionic compounds exist, dissolving in water at least partially.
Thus, if your unknown dissolves in the aqueous NaOH, but does not dissolve in aqueous NaHCO 3, it probably has a functional group with a pKa of between 8 and 14, possibly a phenol. If, on the other hand, your unknown is soluble in the bicarbonate solution, it is likely to have an acidic group with a pKa < 8, probably a carboxylic acid.

- The alcohol is 30% water and 70% alcohol and is not a good dissolver. Alcohol molecules have only one polar area and also have a larger nonpolar area. This makes alcohol not a good dissolver of polar substances. Also, the water and alcohol interact, which means the water doesn’t even dissolve the sugar or color as well as it normally would. Oil
- “Like dissolves like.” Some common solvents are water, methanol, ethanol, ligroin, and toluene. When you use a solvent pair, dissolve the solute in the better solvent and add the poorer solvent to the hot solution until saturation occurs. Some common solvent pairs are ethanol-water,
Hydration occurs when salts dissolve in water. Figure 4.1: (Left) The water molecule is polar. (Right) A space-filling model of the water molecule. Figure 4.3: (a) The ethanol molecule contains a polar O—H bond similar to those in the water molecule. (b) The polar water molecule interacts strongly with the polar O—H bond in ethanol.
Crystals of NaCl dissolve in water, a polar liquid with a very large dipole moment, and the individual ions become strongly solvated. Hexane is a nonpolar liquid with a dipole moment of zero and, therefore, does not significantly interact with the ions of the NaCl crystals.

Is stable in air. Practically insoluble in water. Its solubility in water is increased by the presence of any ammonium salt or of carbon dioxide. The presence of any alkali hydroxide reduces its solubility. Insoluble in alcohol. Dissolves with effervescence in 1 N acetic acid, in 3 N hydrochloric acid, and in 2 N nitric acid.
If you dissolve the mixture in water and then add ether, two layers will form because ether and water are immiscible. Most of the saccharin will be extracted into the ether layer. Any water dissolved in the ether can be removed by utilizing a drying agent such as anhydrous magnesium sulfate (MgSO4)...

Answer (1 of 2): Nacl is a salt, so it's polar and then some, in that each pole has more than a partial charge. Gasoline is a hydrocarbon, so obviously non polar. Ethanol is polar, something you can check by working out it's empiracle formula's shape (C2H6O). Polar substances can be disolved in polar solvents, and non polar so with non polar.
