The VIX index is calculated by the CBOE using option data on SPX options (See Figure 1). In a nutshell it measures the current implied volatility of a subset Jay On The Markets
When an electrochemical cell uses a liquid as an electrolyte, it is called a wet cell. If the electrochemical cell uses a paste as an electrolyte, it is called a dry cell. A automobile battery is an example of a battery of wet cells.A flashlight battery is an example of a battery of dry cells.he electrolyte in the paste of most dry cells is potassium hydroxide. Since potassium hydroxide is a base (an alkaline substance), such cells are known as alkaline batteries. However, acids can also be used as electrolytes for dry cells. In the dry cell, the zinc gives up electrons which enter the paste electrolyte.
Substances that give ions when dissolved in water are called electrolytes. They can be divided into acids, bases, and salts, because they all give ions when dissolved in water. These solutions conduct electricity due to the mobility of the positive and negative ions, which are called cations and anions respectively. Strong electrolytes completely ionize when dissolved, and no neutral molecules are formed in solution. For example, NaCl, HNO3, HClO3, CaCl2 etc are strong electrolytes. An ionization can be represented by, NaCl(s) = Na+(aq) + Cl-(aq) Since NaCl is an ionic solid (s), which consists of cations Na+ and anions Cl-. No molecules of NaCl are present in NaCl solid or NaCl solution.
