RE: THE CHEMISTRY BEHIND WATER TREATMENT: A THEORETICAL AND PRACTICAL APPROACH

in StemSocial2 years ago

HI i got a few questions from reading your article and i do hope you could answer them for me.

I have completed my studie in applied sciences and i was just curious how you were drawn to some of the conclusions and information you wrote down.

The first question i have is of the second image in your article. You say here that the picture shows how oxygen is dissolved in water. However there are only water (diwaterstof mono oxide) images there and no double bond oxigens there. Where do i have to look for the oxygen is my question.

The second question is about the imagine after that. You show a picture of water being added to Hydrochloric acid, and in the reaction formula you say that this acid is in gas form. SO my question is how do you prevent in that example the fast parting of the Hydrogen and the Chloride which will cause a dangerous atmopshere. Normally, as i am thought, you would add acid to water to prevent this, But you show it the other way around. Same goes for the Sodium Chloride situation.

If you have the time to explain that to me i would be very grateful.

Greetings dear friend @dutchchemist, first of all thank you for taking the time to read my contributions and with respect to your approaches they are very good and I will try to give you a clear implication:

With respect to approach 1, notice that in the previous paragraph, I make the caveat so that we make a mental image about a dissolution and I explain that they are formed by solute and solvent, being the latter in greater proportion, so it is to be expected that in our mental image there are many water molecules that interact with each other and that is where the empty spaces in the image, would represent the few places that would occupy the oxygen dissolved in the water.

With respect to your approach 2, no doubt you are right, what I was trying to explain through the image is that both bases and acids, when they behave as strong electrolytes, tend to dissociate and the best way to represent them is through their aqueous phases. At this point, both HCl and NaOH should appear as (aq), i.e. in aqueous solution, so I must modify the respective images because it was an error on my part.

Again I appreciate you taking the time to make the respective observations.
