State Symbols in Chemical Equations | Properties of Matter | Chemistry | FuseSchool

In this video, we will look at the state symbols (s), (l), (g), and (aq) and what they represent in a chemical equation.

For equations to be complete, we must also include the state symbol for each reactant and product.

There are four possible states, each with their own unique state symbol.
Solid – represented by lower case s.
Liquid – represented by lower case l.
Gas – represented by lower case g.
Aqueous, or dissolved in water – represented by lower case aq.

This is written after each reactant or product in brackets and in subscript, meaning, a bit lower than the actual text.

State symbols represent the state of each reactant and each product in a reaction, and must be included in every chemical equation.

0:24 Dammit, I was wearing earbuds at almost midnight...

[maryrosebonello]

how are we meant to know the state symbol if we dont know what certain element symbols stand for?

[adeeladilu]

How will we be able to determine its state by our own ?

[cooldaddy]

What to do when we dont know if it is aquas or solid or liquid or gas??

[ashwingautam]

But Always we don't have obvious elements like H20 know that H2O is aqueous but what to do if there is something like aluminium chloride or zinc chloride in the reactant side or Calcium hydroxide in the reactant side

[artoria]

The state symbol in the new rule isn't subscript anymore, but now it's in the line with the chemical formula and the letters s, l, aq, or g in italic

[kashifmannan]

I dare everyone to go to 2:34 and go to full volume with their headphones on

[animeworld]

Mam can wr write h2+o2 arrow h22o in balanced eguation?

[wendyabaygar]

Can you please answer what does this symbol ( ) mean in chemistry?

[jaspreetkaur]

Great lesson but how do I identify the state of the given reactants and products? Please do answer as you're way of explanation is very helpful.

[jeffreysendall]

i think some hydrogen was produced in my ears there too, thanks for that

[Ayesha______]

Thanks alot this helped me understand state symbols

[sanskritisarraf]

But hcl can also be (l) instead of (aq)

[kalebbeer]

0:24 okay so who is cleaning up the mess i just made... not at all the volume it should have been...
