Why do ionic compounds have high melting point ? |
|
Answer» Because there is a strong electrostatic force of attraction between there charged ions of an ionic compound.so a lot of heat of required to melt or break the ions of an ionic compound.That \'s why ionic compound has high melting and boiling pt. Because ions being oppositely charged have very high intermolecular force of attraction. It requires a lot of heat to separate them from each other |

Can you please tell me what is the PH value in chapter 2.Table 2.2 |
|
Answer» ph stands for power or potential of hydrogen .It can be defined as the negative logarithm of hydrogen ion concentration with base 10. It\'s scale varies from 0 to 14 .If ph is below 7 then the substance is acidic ,if ph is 7 then substance is neutral and if ph is more than 7 then substance is basic in nature. concentration of hydrogen ions in a solutions is called pH value Percentage of hydrogen |

What is electrolytic reaction |
| Answer» Electrolysis is the process by which ionic substances are decomposed into simpler substances when an electric current is passed through them.\tIonic compounds contain charged particles called ions. For example, Sodium Chloride contains positively charged Sodium ions and negatively charged Chlorine ions.\tThe ions must be free to move in order to start the electrolysis process. When an ionic substance is dissolved in water or melted then the ions are free to move. During electrolysis, positively charged ions move to the negative electrode and negatively charged ions move to the positive electrode. Then positively charged ions receive electrons and negatively charged ions lose electrons. Both the products of the dissociation get collected at the electrodes.\tFor instance, if electricity is passed through molten sodium chloride, the sodium chloride is broken into sodium and chlorine and they collect at their respective electrodes. The metals get precipitated and the gases escape. This ability to break down substance with current is used in many ways.\tElectrolysis is widely used for Electroplating. | |
