Dissolve Definition in Chemistry

Dissolve Definition in Chemistry In chemistry, to dissolve is to cause a solute to pass into a solution. Dissolving is also called dissolution. Typically, this involves a solid going into a liquid phase, but dissolution can involve other transformations as well. For example, when alloys form, one solid dissolves into another to form a solid solution. Specific criteria must be met for a process to be considered dissolution. For liquids and gases, the substance that dissolves must be capable of forming non-covalent interactions with the solvent. For crystalline solids, the crystal structure needs to be broken up to release atoms, ions, or molecules. When ionic compounds dissolve, they separate into their component ions in the solvent. The term solubility refers to how readily a substance dissolves in a specific solvent. If dissolution is favored, the substance is said to be soluble in that solvent. In contrast, if very little solute dissolves, it is said to be insoluble. Keep in mind, a compound or molecule may be soluble in one solvent yet insoluble in another. For example, sodium chloride is soluble in water but not as soluble in organic solvents such as acetone or turpentine. Examples Stirring sugar into water is an example of dissolving. The sugar is the solute, while the water is the solvent. Dissolving salt in water is an example of dissolution of an ionic compound. The sodium chloride (salt) dissociates into sodium and chloride ions when it is mixed with water. Releasing the helium from a balloon into the atmosphere is also an example of dissolving. The helium gas dissolves into the larger volume of the air.

Hamilton essays

Hamilton essays One of the biggest problems when facing a new government is the economic problems. Because of the revolution, the federal government had acquired a huge debt of $54 million, including interest, not to mention that the states owed another $25 million. The United States was in need of a new financial program to get them back on sound economic footing. Alexander Hamilton was assigned the task of coming up with a plan to some how resolve these huge debts. As Treasury Secretary, Hamilton designed a financial system that made the United States the best credit risk in the western world. Other countries were more then willing to let the United States borrow money. Hamilton proposed that the government assume the entire debt of the federal government and the states. Many people were very skeptical of this plan, but he went through with it. His plan was to retire the old depreciated obligations by borrowing new money at a lower interest rate. Some States such as Maryland, Pennsylvania, North Carolina, and Virginia, which had already paid off all their debts, saw no reason why they should be taxed by the federal government to pay off the debts of other states like Massachusetts and South Carolina. For six months, a bitter debate raged in Congress, until James Madison and Thomas Jefferson engineered a compromise. In exchange for southern votes, Hamilton promised to support locating the national capital on the banks of the Potomac River, the border between two southern states, Virginia and Maryland. Hamilton's debt program was a huge success. By demonstrating Americans' willingness to repay their debts, he made the United States attractive to foreign investors. European investment capital poured into the United States in large amounts. The next problem that Hamilton had to face was making a National Bank. He wanted to model it after the bank of England. The national bank would collect taxes, hold government funds, and make loans to the gove...
