Acids

[Tracey Tran 3I]

What acids are we expected to know?

[Ada Chung 1C]

He hasn't gone into depth on this topic yet so I feel like we would know more maybe next week. For now, I think he has mentioned strong acids like HCl as well as several weak acids. Knowing the strong acids would be important in knowing that they are completely ionized in an aqueous solution.

[Jessica Tran_3K]

I think knowing the 7 common acids would be helpful! They are:
hydrochloric acid. HCL.
hydrobromic acid. HBr.
Hydroiodic acid. HI.
Nitric acid. HNO3.
Perchloric acid. HClO4.
Sulfuric acid. H2SO4.
Chloric acid. HClO3

[Brian J Cheng 1I]

Dr. Lavelle will most likely give us an idea on which specific acids we should know but the most common acids (shown above) are a good place to start!

[Kaitlyn Jang 1F]

There is no specific list but it’ll be helpful to remember the 7 most common acids.

These are the 7 main ones you should definitely know!

[Anvi Brahmbhatt 4A]

Know the 7 most common acids mentioned above!

[AngieGarcia_4F]

Probably the 7 main strong & weak acids he went over in class, and we will probably have to know bases too, but i'm sure Dr. Lavelle will tell us as we get closer to the final.

What acids are we expected to know?

As mentioned above, I don't think there is a specific list of acids that we are expected to know. However, in lecture today, Dr. Lavelle did go over trends on acid/base strength. Based on that, I think he would probably expect us to know acid/base strength not based on memorization, but rather periodic trends. Thus, I think it's better to understand the concepts, rather than a memorized list.

[Aman Sankineni 2L]

He will probably ask questions about acid/base strength based on the list given. As long as you know how to find strength, you would be able to answer the questions based on those 7.

A good list to know is this list of 7 strong acids: HCl, HBr, HI, H2SO4, HNO3, HClO3, HClO4
Also know that generally molecules with COOH are weak acids.

[KMenjivar_3A]

Any molecule that contains a hydrogen or H+ that molecule will most have a high acidity. And basics will usually have an OH-

is H2SO4 different from the others because it has two Hydrogens?

It's different in that H2SO4 can dissociate twice, meaning it is polyprotic:
H2SO4 + H2O <-> H3O+ + HSO4-
HSO4- + H2O <-> H3O+ + SO4 (2-)
