The answer is because like electric charges do not attract with each other. Ions either lack or have excess electrons in their atomic structure. Ions with a positive charge are called cations. They lack electrons in their atoms so they have to pair up with negatively charged ions, called anions, because they have excess electrons. Together, they form a compound that is neutral.
Answer:
A pathway by which counter ions can flow between the half-cells without the solutions in the half-cell totally mixing.
Explanation:
Salt bridge is a link between oxidation half and reduction half of a galvanic cell.
Functions of salt bridge are:
Maintaining electrical neutrality
Preventing cell from reaching equilibrium
For creating salt bridge, a U shaped glass tube is filled with an inert electrolyte. Electrolytes used in the salt bridge generally do not reacts with the cell chemicals.
Cations and anions of the electrolytes have same ionic conductivity and hence, migrate with the same speed.
Most commonly potassium chloride, sodium chloride and potassium nitrate are used as an electrolyte in salt bridge.
Electrolyte are generally mixed with agar agar to prevent mixing of chemicals in the two half cells.
Inhales. Oxygen - good for the body - gives it to the Circulatory System to be transported throughout the body through the blood. Digestive System gets nutrients from food and hands it over to the blood and Circulatory System then carries those nutrients where they need to go.
I hope this helps! :')
