Concentration of ions in a reaction

[Trooper100]

Alright guys, I am a little bit confused on how to find the concentration of ions in a reaction. In a solution, it is relatively easy.

Are the number of ions in the beginning the same they are in the end?

Please give me some general guidelines: i know to begin with a balanced equation , then a net ioc equation...but how does the net ionic equation help me??

Thank you so much, I will further update this question...so I can't specifically put my questions into words!

Any help appreciated, thank you so much.

What do you mean by "the concentration of ions in a reaction"? Do you mean that you need to find the concentration of a solution after a reaction?

Are the number of ions in the beginning the same they are in the end?

Not necessarily. Ions may be involved in many reactions where gases, precipitates, other ions etc. are formed, so the number of ions after a reaction will not generally be the same as before the reaction.

Could you provide a specific example of what you are trying to do?

I believe this is a dangerous wording (even if correct), as it may be read by someone that mass conservation is violated. And knowing students if something can be understood incorrectly, it will be.

Heck, even if something is worded in a way that can't be understood incorrectly, it will, against all odds.

Number of ions can change, but those that have "disappeared" are still there, just in different form. Number of atoms of an element (in all oxidation states) have not changed.

Ok...thanks for the help anyway. I think I got it, thank you everyone.

I would like to provide some guidance on how to determine the concentration of ions in a reaction. First, it is important to understand that in any chemical reaction, the number of ions present in the beginning will be the same as the number present in the end, as atoms are neither created nor destroyed during a reaction. However, the way in which these ions are distributed may change.

To determine the concentration of ions in a reaction, you will need to know the initial concentration of the reactants and the stoichiometry of the reaction. This can be obtained from the balanced chemical equation. From there, you can use the molar ratio of the reactants and products to calculate the concentration of ions in the final solution.

The net ionic equation can also be helpful in determining the concentration of ions in a reaction. This equation shows only the species that are directly involved in the reaction, omitting any spectator ions. By focusing on the ions that are actually participating in the reaction, it can be easier to determine their concentration.

In general, to find the concentration of ions in a reaction, it is important to have a good understanding of stoichiometry and use the appropriate equations and calculations. Additionally, it is important to accurately measure the initial concentrations of the reactants and account for any changes in volume or dilution during the reaction. I hope this helps and feel free to provide more specific questions for further assistance.

I can provide some guidance on how to determine the concentration of ions in a reaction. The first step is to start with a balanced chemical equation, which shows the reactants and products involved in the reaction. From this equation, you can determine the molar ratio of ions present in the reaction.

Next, you will need to know the initial concentration of the reactants in the solution. This can be determined by measuring the amount of each reactant added to the solution or by using known molarities of the reactants.

The net ionic equation is helpful because it only shows the ions that are directly involved in the reaction, making it easier to determine the molar ratio of these ions. This can then be used to calculate the concentration of each ion in the solution at the end of the reaction.

It is important to note that the concentration of ions may change throughout the reaction, as some ions may be consumed or produced. Therefore, it is necessary to measure the concentration of ions at multiple time points during the reaction to get a more accurate understanding of the ion concentration changes.

I hope this helps to clarify the process of determining the concentration of ions in a reaction. If you have any further questions, please feel free to update your question and I will do my best to assist you.
