(a)
Interpretation:
For “An oxidizing agent”, the oxidation number increase or decrease in the
Concept introduction:
Redox reaction: Redox reaction is a type of
Oxidation number:
The oxidation number of an element is zero. The oxidation number of a monoatomic ion equals its charge.
The oxidation number is zero for the summation of the oxidation numbers complete atoms in a complete formula.
The charge on the ion is equal to the summation of the oxidation numbers of complete atoms in poly atomic ion.
The oxidation state of alkali metal
The oxidation state of hydrogen is
An oxidizing agent gains the electrons and is reduced in a chemical reaction and it is electron acceptor.
A reducing agent loses electrons and is oxidized in a chemical reaction and it is electron donor.
The oxidation state is called as oxidation number, which describes degree of oxidation (loss of electrons) of an atom in a chemical compound. Theoretically, the oxidation state is positive, negative or zero.
(b)
Interpretation:
For “A reducing agent”, the oxidation number increase or decrease in the redox reaction has to be identified.

- Write the net ionic equation for the reaction, if any, that occurs on mixing (a) solutions of sodium hydroxide and magnesium chloride. (b) solutions of sodium nitrate and magnesium bromide. (c) magnesium metal and a solution of hydrochloric acid to produce magnesium chloride and hydrogen. Magnesium metal reacting with HCl.arrow_forwardMany over-the-counter antacid tablets are now formulated using calcium carbonate as the active ingredient, which enables such tablets to also be used as dietary calcium supplements. As an antacid for gastric hyperacidity, calcium carbonate reacts by combining with hydrochloric acid found in the stomach, producing a solution of calcium chloride, converting the stomach acid to water, and releasing carbon dioxide gas (which the person suffering from stomach problems may feel as a “burp”). Write the unbalanced chemical equation for this process.arrow_forwardComplete the missing information in the following skeletion equation and balance the chemical equation: NaOH(aq)+3NaCl(aq)+Al(OH)3(aq)arrow_forward
