In electrochemistry, a salt bridge or ion bridge is a laboratory device used to connect the oxidation and reduction half-cells of a galvanic cell (voltaic cell), a type of electrochemical cell. It maintains electrical neutrality within the internal circuit.

Redox couples are analogous to conjugate acid-base pairs and behave in much the same way. The stronger an oxidizing agent, the weaker the corresponding reducing agent, and the stronger a reducing agent, the weaker the corresponding oxidizing agent. For example, in a galvanic cell, the two redox coupRead more

The stronger an oxidizing agent, the weaker the corresponding reducing agent, and the stronger a reducing agent, the weaker the corresponding oxidizing agent. For example, in a galvanic cell, the two redox couples are represented as Zn²⁺/Zn and Cu²⁺/Cu.
The solutions which obey Raoult’s law over the entire range of concentration are known as ideal solutions. The ideal solutions have two other important properties. The enthalpy of mixing of the pure components to form the solution is zero and the volume of mixing is also zero, i.e., ∆mixH = 0, ∆mixVRead more

All these properties depend on the number of solute particles irrespective of their nature relative to the total number of particles present in the solution. Such properties are called colligative properties.

The ebullioscopic constant is also called the molal elevation constant. It is defined as the elevation in boiling point when one mole of non-volatile solute is added to one kilogram of solvent. It is denoted by Kb. The unit of an ebullioscopic constant is K Kg mol⁻¹.
