1. suggest an order for the conductivity of H+, Cl- and OH-, explain your reasoning
2. (so I have a conductivity data)....Which of the solutions have ions due to the presence of solute?
b. Are there covalent solutes that produced ions in solute?
You need to write more of what you have in order for us to be able to help you.
ok.
Solutions: The H+ ions and OH- ions move under the influence of an electric field by very different processes than Na+ or Cl- ions. Consider your conductivity values for the 0.010 M solutions of NaCl ( 12.80), NaOH (1480), and HCl (1.083E). Suggest an order for the conductivity of H+ ions, Cl- ions, and OH- ions.
2. I have a conductivity table with values but don't know how to use it...
1. To determine the order of conductivity for H+, Cl-, and OH-, we need to consider their electrical charges and mobility.
- H+ (Hydrogen ion) has a positive charge and is a highly mobile ion. It can easily move through a solution, making it a strong conductor.
- Cl- (Chloride ion) has a negative charge and is also a highly mobile ion. It can conduct electricity well through a solution.
- OH- (Hydroxide ion) has a negative charge, but it is not as mobile as H+ or Cl-. It has a lower conductivity compared to the other two ions.
Based on this information, the order of conductivity is:
H+ > Cl- > OH-
2. To determine which solutions have ions due to the presence of solute, we can use the concept of electrolytes. Electrolytes are substances that produce ions in solution and can conduct electricity.
a. If a solution allows electricity to pass through, it indicates the presence of ions. Hence, solutions that have a high conductivity and allow the passage of electric current are the ones with ions due to the presence of solute.
b. Covalent solutes typically do not dissociate into ions in solution, meaning they do not produce ions. However, there are exceptions where covalent compounds can ionize or dissociate in the solution, forming ions. For example, strong acids such as hydrochloric acid (HCl) can dissociate into H+ and Cl- ions, even though it is a covalent compound.
To determine if a covalent solute produces ions, you can refer to reference materials like chemical literature or databases, which provide information about the solute's ionization behavior in a solution.
