![]() Hence, by remembering LOAN mnemonic, we can arrive at the corresponding properties for the cathode. Obviously, the opposite properties (Right/Cathode/Reduction/Positive) are found on the cathode. It is the electrode where oxidation takes place. In written representation of galvanic cell, anode is written on the left. Reduction Involves Gaining electrons at the CAThode. reduction: electrochemical cell and electron gain/lossĪt the ANode, Oxidation Involves Loss of electrons. The t in cation looks like a plus sign: “ca+ion”. ![]() This can be remembered with the help of the following mnemonics.Ĭa+ion: The letter t in cation looks like a + (plus) sign.Īn anion is a negative ion. Oil Rig: Oxidation is loss Reduction is gain (of electrons).Ĭations are positively (+) charged ions while anions are negatively (−) charged. Leo says Ger! or Leo the lion, Ger! can be used to represent Loss of electron is oxidation Gain of electron is reduction. This relation can be remembered by the following mnemonics. The atom whose oxidation number decreases gains (receives) one or more electrons and is said to be reduced. It is accomplished by loss of one or more electrons. Popular Scientists Can Make A Zoo In The Low Humid Country More(Mercury) Satisfactorily (Gold).Ī redox reaction is a chemical reaction in which there is a change in oxidation state of atoms participating in the reaction.Īn atom (or ion) whose oxidation number increases in a redox reaction is said to be oxidized (and is called a reducing agent). Potassium > Sodium > Calcium > Magnesium > Aluminium > Zinc > Iron > Tin > Lead > Hydrogen > Copper > Silver > Gold Only Strong Athletes In College Study Past MidnightĪs they are present in trace quantities they are measured in parts per million(ppm). Larry’s Half Taken, Wendy Reached Out H(I)er Plate Audibly, Helga. Yes S(Z)ir, Niobi and Most Technicians Rub Rhonda Padilla’s silver(Ag) Cadillac. Scary Tiny Vicious Creatures are Mean Females Come to Night to Club Zen. Note: After the k shell, they follow alphabetical order (skipping s and p as they came earlier). Sober Physicists Don’t Find Giraffes Hiding In Kitchens. This article contains the list of certain mnemonics in chemistry. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics. A mnemonic is a memory aid used to improve long term memory and make the process of consolidation easier.
