A weak acid has a pK value of 3.8. A solution contains 0.1 M of the acid and 0.3 M of the negatively charged ion. What is the pH of the solution? Express the result to two decimal places. pH =
3.8 – 0.1Мx – 0.3Mx=0.3*3.8/0.1=11.4

What does it mean to say that an acid is a strong acid? How is a strong acid different from a weak acid?
Strength of the acid is determined by its dissociation, more exactly – by its dissociation constant: AxBx = xA + yB Kd = [A]x [B]y / [AxBy] Strong acids dissociate...

1.) For each of the following, indicate whether it is a:
1. Strong acid, 2. Weak acid, 3. Weak base, 4. Strong Base
A. HCl
B. acetic acid
C. Iactic acid
D. H2SO4
E. Ca(OH)2
A. HCl - strong acid; B. Acetic acid - weak acid; C. Lactic acid - weak acid; D. H2SO4 - strong acid; E. Ca(OH)2 - strong base.

Identify the conjugate base for each acid.
conjugate base of H2CO3
conjugate base of HSO4−
conjugate base of NH4+
Conjugate base of H2CO3 HCO3-Conjugate base of HSO4- SO42-Conjugate base of NH4+ NH3

Identify the conjugate acid for each base.
conjugate acid of HSO4−
conjugate acid of SO42−
conjugate acid of NH3
Conjugate acid is formed by adding an H+ ion to the given base.So ,Conjugate acid of HSO4- is H2SO4.Conjugate acid of SO4-2 is HSO4-Conjugate acid of NH3 is NH4+

What are the similarities and differences between strong and weak acids?
Both strong and weak acids.....
Only strong acids.....
Only weak acids.....
Both strong and weak acids are ionized in aqueous solutions, depending on their strength. Strong acids only ionize almost completely in water; hence, nearly all the H+ ions are released.Weak...
