# What's wrong with my question?

From my perspective:

• Is it related to chemistry? yes
• Is it a low effort post? no; clearly asked what I need and provided example of possible solution for which I am seeking validation

Now, is it an easy question? Probably. Maybe trivial to most people? Probably. But one cannot assume something obvious to some is obvious to all.

Closed as:

Homework questions must demonstrate some effort to understand the underlying concepts.

This is not even a homework question (though I see your definition of homework is quite broad), just having a simple doubt and seeking confirmation from more experience users in this field.

I really can't understand why such question should be closed. If it were allowed to stay open I bet someone would have answered sooner or later. If not I'd have started a bounty for some user to gain some points.

As this is your first question here, (and there aren't other examples I can use), let's go through this from my point of view.

Considering a solution which is 20% Benzalkonium chloride and 80% water. Placing 10ml of such solution in 3700ml of water, how can I calculate the final concentration?

This is a vague thing in the first place. There are more than one type of percentages used to measure mixtures and this can be any one of them. However, from context, I can assume it's $$V/V\%$$. (Starts to look like a homework question to me, possible one liner of an answer, time to look for the effort put in)

We obtain a solution of 3710ml total, out of which 2ml are supposedly Benzalkonium chloride. Is the final concentration thus 2/3710*100 = 0.05% ?

Alright, you have given effort to the question. Maybe some formatting was in order, however that is excused. The major issue I see here though is that it has now become a question with a very simple answer. "Yes, you are correct." :(

Somebody could/should have responded in the comments but otherwise this is a question I would vote to close as well.

Sorry for your bad first experience here. Hope this doesn't ruin the fun of studying chemistry. Welcome to Chem SE

• I thank you for taking the time to reply and I agree with you: I would have welcome a comment by all the people who voted to close. I don't care if I get my answer in a comment or via reply. I just don't get how SE has become at all. I have used SEs for almost 12 years and I'm just shocked how it changed. I think the main purpose of these sites should to provide answers to people seeking them; instead it seems one should worry just about creating great content for SEs. I need help - I ask question. Don't want to help? Let some other do instead of closing. Aug 9 at 19:25
• @JoeSlav CH SE wants some quality level of the set of its Qs/As. There is no point in providing answers which already exist in hundreds of variants over internet and textbooks, like weak acid salt solution pH, which could be find easily and quickly. Or the trivial cases of solution dissolving // I often add: The site expects that you write explicit compact summary of your prior effort to answer the question, based on your knowledge and on searching for existing related info or answers. It helps preventing others to tell you what you already know or what you could easily find yourself. Aug 10 at 9:52
• @JoeSlav If you understand the procedure properly, you do not need confirmation, you can do it yourself. If you do not understand it properly, you do not need confirmation either, you need to understand the procedure. For the latter, search for the procedure first. Aug 10 at 10:09
• @Poutnik, exactly! The point of these websites is now to create quality content as opposed to help users. Users will be helped if they google stuff up and find Q/A but the actual users posting questions are basically tools and none cares. At least this is my opinion. See my comment below for possible better way to approach this. Cheers. Aug 10 at 18:08
• @JoeSlav I really do hope you stick around. Aug 10 at 20:44
• @JoeSlav Helping users means giving them what they need, not what they want. If a user did research, he should show the summary. Taking the user's word for it is tricky, as many times "I have searched internet and found nothing" means "I have not done even basic Google search with few mentioned keywords". Aug 10 at 23:27
• @JoeSlav " Since my SE beginnings like 7y ago, all SE sites I took part profiled themselves not just being Q/A sites (as many webforums or Quora site do), but also keeping policy of some quality level for these Qs/As, like moderated Usenet groups did in old good times. This distinguishes SE from many sites that have minimal to no quality requirements. One can always post his question on Quora if one does not like it. Aug 18 at 14:07
