(aq) means the solution is dissolved in water used as a solvent. (l) means the COMPOUND (not element, usually) is a pure liquid. (g) means gas and (s) means solid.
In the equation below,
HCl(aq) + NaOH(aq) -->NaCl(aq) + H2O(l)This means that an aqueous solution of HCl is mixed with an aqueous solution of NaOH. The products are an aqueous solution of NaCl and pure water. (Of course the water isn't pure anymore when mixed with the aqueous solution of NaCl but I guess that is obvious.)
What is the difference between (aq) and (l) ...what do they mean.
I know Aq is a aueous solution while (l) is a liguid with only one element...but what is the difference between them?
thanks
A solution in which water is the dissolving medium or solvent. It's a solute dissolved in water
thats the definition for aqueous solution
The difference between (aq) and (l) in chemical equations is in the state of the substance being represented.
(aq) stands for "aqueous," which means that the substance is dissolved in water, resulting in an aqueous solution. In the equation you provided, HCl(aq) and NaOH(aq) represent aqueous solutions of hydrochloric acid and sodium hydroxide, respectively. This means that these substances are dissolved in water to form a solution. Aqueous solutions are typically indicated by the presence of water (H2O) as the solvent and are often used in chemical reactions.
On the other hand, (l) stands for "liquid," indicating that the substance is a pure liquid state. In the given equation, H2O(l) represents pure water, which is the product of the reaction between HCl(aq) and NaOH(aq). The (l) is used to differentiate water as a distinct liquid product in this equation.
So, to summarize, (aq) indicates that a substance is dissolved in water to form an aqueous solution, while (l) represents a pure liquid state.
