Following is a question that was sent to me recently by a local students.
This is a question based on the Properties of Acids and is getting popular in many of the Preliminary Exams in local Top Secondary Schools.
Quick Check 1:
Sulfuric acid is a dibasic acid because:
A. each molecule contain 2 hydroxide ions
B. each molecule can produce 2 hydrogen ions
C. one mole of the acid contains two atoms of hydrogen that can be replaced by a metal
D. sulphuric acid can only be neutralized by 2 bases
E. sulphuric acid has the usual properties of an acid, but is also a dehydrating agent
Try working out the question before checking the answer and reasoning below.
Answer to this Multiple Choice Question is (B). =)
Who got the correct answer???
Reasoning:
An acid is defined as a compound, which produces hydrogen ions (H+) as the only +ve ions when dissolved in water.
Basicity of an acid refers to the number of replaceable hydrogen atoms in one molecule of the acid.
Sulfuric acid (H2S04) is an example of Dibasic acid as one molecule of it contains 2 atoms of H and so every molecule of it forms 2H+ ions when dissolved in water. We say the BASICITY of Sulfuric Acid is 2.
Since we have Dibasic acid, we will also have Monobasic and Tribasic.
For Monobasic, we have HCl, HNO3, CH3COOH, etc. You get it????
For Tribasic, can you share with us an example you can think of???
this is awesome keep the good work for us.
sure! I would if I need any doubts, thanks! 🙂
Hi Joe,
Thank you for your comment.
I am glad that as a Sec 3 student, you are already so driven to do well academically for Chemistry. Way to go!
With regards to MSN, i do not use it that often.
You can send an email to me at sean@SimpleChemConcepts.com if you need clarification for any question on Chemistry.
PS: Do note that my response will not be immediate as i am involved in several coaching workshops, projects as well as writing my 2nd Chemistry book.
Meanwhile, do check out other questions on this blog and particpate as you learn.
To Your Academic Success in Chemistry.
