Interpretation:
Visible light will cause
Concept Introduction:
Photoelectric effect: It is the process in which electrons emit or other free carriers when photons strike a metal surface. These emitted electrons are known as photoelectrons. The phenomenon of ejection of electrons from metal surface is called as the photoelectric effect.

- You wish to add enough NaOCl (sodium hypochlorite) to a 150 m³ swimming pool to provide a dose of 5.0 mg/L TOTOCI as Cl2. (a) How much NaOCI (kg) should you add?
