what substance was added in a little quantity of water how did it help to take the reaction?
Answers
Answer:
And, water is called the "universal solvent" because it dissolves more substances than any other liquid. ... Water can become so heavily attracted to a different molecule, like salt (NaCl), that it can disrupt the attractive forces that hold the sodium and chloride in the salt molecule together and, thus, dissolve it.
At 20 °C one liter of water can dissolve about 357 grams of salt, a concentration of 26.3%.
This chapter focuses on different behavior of water, that is, solutions and solubility. 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 the solvent at that temperature. Whenever a substance is described as soluble or insoluble in a solvent it is taken for granted, unless otherwise stated, that the temperature is about room temperature. If the solid disappears, the substance is obviously soluble. When a bottle of soft drink is opened, bubbles of the dissolved gas, carbon dioxide, are seen leaving the liquid. If the soft drink is warmed, more bubbles of the gas leave the liquid because in general, gases are less soluble in hot liquids than in cold liquids.
