State symbols are used to show the physical state of reactants and products in a reaction, at the reaction temperature. This means the temperature at which the reaction takes place. State symbols are shown in subscript, just like when we use numbers to show how many atoms are in a molecule such as diatomic oxygen (O₂).

Nov 21, 2017 · So its state symbol will be $\text{(aq)}$. Hydrogen on the other hand is a gas (at room temperature and above) and highly insoluble in water: it will leave the reaction as gas and its state symbol will be $\text{(g)}$. So without knowing the physical/chemical properties of the reagents/reaction products, the state symbols cannot be determined.
Solid, Liquid, Gas & Aqueous. State symbols are written after each formula in chemical equations to show which physical state each substance is in. Brackets are used and they are not usually subscripted although you may come across them written in this way. Aqueous should remind you of the word 'aqua' and means the substance is dissolved in water.

May 16, 2024 · There are four common symbols used for depicting physical states. These are (s), (l), (g) and (aq). Let us discuss each term one by one. (s) stands for solid state of matter. Compounds which are solid in state, can be either reactant or product such as limestone and quicklime in the following reaction. (l) stands for liquid state of matter.
2 days ago · Oxidation refers to a chemical reaction that involves electron movement between the elements of any compound. The process’s character is exhibited when an element donates electrons. It is also denoted by an increased oxidation state. A common example of oxidation is the reaction of iron (Fe) with oxygen (\ [O_ {2}\]).
Mar 7, 2018 · States of aggregation should not be subscripted, it is not wrong, but the recommendations (Sec. 2.1.) are different.. The document recommends that: The symbols should be printed in roman type without full stops (periods) and should be placed in parentheses after the symbol for a physicochemical quantity or chemical substance to which they relate.
