Electrolysis

This document provides the curriculum for the ICS 300 course, which trains responders in managing expanding incidents. Learn about ICS fundamentals for complex events, unified command, resource management, and planning processes for larger-scale emergencies.

Prepare for your Electrology state board exam with this comprehensive guide covering the IBEC (International Board of Esthetics & Cosmetology) core curriculum and laser hair removal protocols. This essential resource includes key concepts, practice questions, and study material for both traditional electrolysis and modern laser modalities to help you pass your certification.

oxidation - gaining oxygen OR losing electrons reduction - losing oxygen OR gaining electrons electrode - conducting rod made of metal or graphite that carries the current in/out of the electrolyte solution - an ionic solid dissolved in water metal - product formed at the negative electrode (cathode) non-metal - product formed at the positive electrode (anode) Reason solid ionic compounds cannot conduct - The ions have a fixed position and cannot move

What happens to Pb2+ at the cathode? - a lead ion accepts/gains two electrons to become a lead atom. (Pb) What happens to the molten lead formed at the cathode when Pb2+ gains 2 electrons? - it will sink to the bottom. what is the half equation to show what happens to Pb2+ at the cathode? - Pb2+(l) + +2e - ---> Pb(l) Which electrode are the bromide (Br-) ions attracted to? - the anode (positive electrode) what happens to Br- at the anode? - Two bromide ions lose one electron each and...
