What is ha in chemistry?

[Cajous]

What is HA and the difference between HA, H+ and A-?

Any definition will be helpful.

 

[medstudent]

HA is the acid - a proton and its conjugate base, H+ is the proton released when the acid dissociates in water (can also be written as H3O+, the hydroxonium ion) while A- is the conjugate base.

 

[Centrino]

• HA = undissociated acid molecule like CH3COOH
• H+ = short hand for H3O+
• A- = conjugate base of HA

Oh thanks guys!! I was having problem with differentiating what they really are, but using them with calculations isn't a problem for me.

can you help me explain how they work with their conjugate base?

For example, if you have HCI as the acid, Cl- will be its conjugate base.

 

[Cajous]

Another example is when you have CH3COOH as the acid, CH3COO- will be its conjugate base.

Oh okay.. more of like having HNO3 as acid, NO3- as conjugate base

 

[Cajous]

Correct!!

Correct!!

Ok got it
