Which of the following is not a generally used electrolyte in the salt...
Explanation:

Electrolytes are used in salt bridges to maintain electrical neutrality by allowing the flow of ions between the two half-cells of an electrochemical cell. The commonly used electrolytes in salt bridges are NaCl, KNO3, and KCl.

The correct option is (D) ZnSO4, which is not a generally used electrolyte in salt bridges. This is because ZnSO4 can react with the electrodes, leading to unwanted side reactions.

The reasons for the selection of the commonly used electrolytes are:

1. NaCl: It is a cheap and abundant salt that is easily available. It is also stable and does not react with the electrodes.

2. KNO3: It is a strong oxidizing agent and is used in salt bridges for redox reactions. It also has a high solubility in water and does not react with the electrodes.

3. KCl: It is the most commonly used electrolyte in salt bridges. It is stable, does not react with the electrodes, and has a high conductivity.

Conclusion:

The commonly used electrolytes in salt bridges are NaCl, KNO3, and KCl. ZnSO4 is not a generally used electrolyte in salt bridges due to its reactivity with the electrodes.

Which of the following is not a generally used electrolyte in the salt...
A salt bridge is a device used to connect the oxidation and reduction half-cells of a galvanic cell (a type of electrochemical cell). Strong electrolytes are generally used to make the salt bridges in electrochemical cells. Since ZnSO4 is not a strong electrolyte, it is not used to make salt bridges.

Similar Class 12 Doubts

Read the following text and answer the following questions on the basis of the same:Supercapacitor: Super capacitor is a high capacity capacitor with a capacitance value much higher than normal capacitors but with lower voltage limits. Such capacitors bridges the gap between electrolytic capacitors and rechargeable batteries. In automobile, bus, train, crane, elevator such capacitors are used for regenerative braking, short term energy storage or burst-mode power delivery. Super capacitors have many advantages over batteries: they are very low weight and generally don't contain harmful chemicals or toxic metal. They can be charged and discharged innumerable number of times without ever wearing out. The disadvantage is that super capacitors aren’t well-suited for long-term energy storage. The discharge rate of super capacitors is significantly higher than lithium-ion batteries; they can lose as much as 10-20% of their charge per day due to self discharge.Super capacitor makes a bridge between
