Explanation

Acetic acid (CH3COOH) is a weak acid that only partially dissociates in water, forming a weak electrolyte solution.

It does not fully dissociate into ions like strong acids (like HCl) or strong bases (like KOH).

Explanation

Sodium hydroxide (NaOH) is a strong electrolyte because it completely dissociates into ions in water.

It conducts electricity well.

It is used in many industrial processes.

Explanation

In a dry cell, the electrolyte is a paste of ammonium chloride mixed with zinc chloride.

This paste allows the flow of electric current by enabling the movement of ions within the cell.

Explanation

NaCl is an electrolyte.

Because it dissociates into ions (Na+ and Cl-) in water, conducting electricity.

Explanation

• A voltaic cell is an electrochemical cell that makes use of a chemical reaction to supply electrical energy. Zinc is used as anode and copper is used as cathode.
• The voltaic cell makes use of  extraordinary metal electrodes, each in an electrolyte answer. The anode will go through oxidation and the cathode will undergo reduction. The steel of the anode will oxidize, going from an oxidation kingdom of zero (in the solid form) to a positive oxidation nation, and it becomes an ion. at the cathode, the steel ion within the answer will accept one or extra electrons from the cathode, and the ion’s oxidation kingdom will lessen to 0.
• This paperwork a strong steel that deposits on the cathode. the two electrodes ought to be electrically linked to each different, taking into consideration a go with the flow of electrons that depart the metal of the anode and glide thru this connection to the ions on the surface of the cathode. This float of electrons is an electrical modern-day that can be used to do work, inclusive of flip a motor or electricity a mild.

Explanation

Explanation

Hypotonic sports drinks contain a low level of carbohydrates.

They can quickly replace fluids that are lost by sweating and provide some energy in the form of sugar calories.

They are suitable for athletes who need fluids without a significant boost of carbohydrates.

Explanation

•  02% of total body potassium is present in the extracellular fluid of a person
  

Explanation

Molten NaCl conducts electricity because of the presence of free ions. 

When sodium chloride (NaCl) melts, the ionic bonds holding the sodium (Na+) and chloride (Cl-) ions together break, allowing them to move freely within the liquid.

These mobile ions can carry electrical charge, thus enabling the molten salt to conduct electricity. 

Explanation

A normal potassium level for adults is between 3.5 and 5.5 millimoles per liter (mmol/L).

Potassium level is high (also called hyperkalemia) when it goes above 5.5 mmol/L.
