Factors that Determine a Strong and Weak Electrolyte

Strong electrolytes: They are called “strong electrolytes” when they are almost completely ionised when they are dissolved in water or when they are fused together.

Examples: Mineral acids, alkalis, and salts are found in the Earth’s crust.

Weak electrolytes: Weak electrolytes are compounds that aren’t very ionised when they’re fused together or when they’re mixed with water. They don’t conduct electricity very well.

Examples: Acetic acid, oxalic acid

Factors that Determine a Strong and Weak Electrolyte

(1) The nature of an electrolyte: The conductance of an electrolyte is determined by the number of ions in it. Because there are more ions in the solution, the more conductance there will be, so this is why. The number of ions that an electrolyte makes depends on how it is made. The strong electrolytes break down almost completely into ions in solutions, so their solutions have a lot of conductivity. Weak electrolytes, on the other hand, only break apart to small amounts and give out fewer ions than strong electrolytes do. The solutions of weak electrolytes have low conductance, so this is why.

(2) The concentration of the solution : The molar conductance of electrolytic solution changes with the concentration of the electrolyte in the solution. In general, the molar conductance of an electrolyte goes up when the concentration or the dilution goes down.

Strong electrolytes and weak electrolytes both have more molar conductance when their concentration or dilution goes down or up. However, the difference between strong and weak electrolytes makes a difference in the change.

The change in molar conductance with concentration can be explained by how well ions can move through weak and strong electrolytes.

There are more or less ions in a solution for weak electrolytes, which means that when you dilute them, they change in different ways. When an electrolyte is in solution, the number of ions it gives off depends on how dissociated it is when it is diluted. With more dilution, the amount of dissociation increases, which means the amount of molar conductance increases. This means that the limiting value of molar conductance is 1 i.e., all of the electrolyte breaks down.

Strong and weak electrolytes’ nature :

Weak electrolytes don’t completely break down into the solvent.

The solution has both molecules and the ions that are in the electrolyte, which are found in the solution. In water, weak electrolytes ionise some of the time, but strong electrolytes ionise all the time Weak bases and weak acids are electrolytes that are not very strong. A strong electrolyte is one that has a lot of strong bases, strong acids, and salts in it. It doesn’t matter how much salt dissolves in water because it is a strong electrolyte even though it has a low solubility. All the salt that dissolves in water is completely ionised.

Electrolytes that completely break apart in solution are called strong electrolytes. A strong electrolyte is a solute or solution with a lot of them. The electrolyte will only be in the solution in the form of ions and not molecules.

Strong electrolytes have a degree of dissociation close to 1 and weak electrolytes have a degree of dissociation that is less than  1.

Strong electrolytes are good at transferring electricity, but only when they’re in water or when they’re hot.

Identifying strong and weak electrolytes

This is how we know whether a substance is strong, weak, or not electrolyte when it is mixed with water (aqueous solution).

1. All ionic compounds are strong electrolytes because they mostly break down into ions when they dissolve in water. This means that they are good electrolytes. As you know, even ionic compounds that aren’t soluble in water are strong electrolytes because the small amounts that do dissolve in water do so mostly as ions; there is almost no undissociated form of the compound in the solution.
2. Molecules can be non-electrolytes, weak electrolytes, or strong electrolytes, depending on how they dissolve. If they don’t dissolve at all, a little, or mostly, they are non-electrolytes.
3. Strong acids and strong bases are strong electrolytes [e.g., HCl(aq), H2SO4 (aq), HClO4 (aq); NaOH(aq)].There are almost no molecules of a strong acid or base in solution. Instead, there are only ions in the solution.

Conclusion :

Electrolytes are found in fruit juices, milk, nuts, vegetables, and many fruits. They are also found in a lot of fruit. The two types of electrolytes are strong and weak, and they come in both types. The bases and acids can be strong bases and acids or weak bases and acids. Diagnostic procedures can be used to measure electrolytes. In these procedures, blood is tested with ion-selective electrodes. A lot of people measure potassium and sodium as electrolytes.

When strong electrolytes are melted or mixed with water, they can pass electricity. There are no more ions in strong electrolytes. An electrolyte that is stronger will make a bigger voltage in a galvanic cell when it is used with one.
