Which of the following solutions is a strong acid?

a. 0.1 M {eq}HCl {/eq}

b. 0.1 M {eq}HC_2H_3O_2 {/eq}

c. 0.1 M {eq}NaOH {/eq}

d. 0.1 M {eq}NH_3 {/eq}

Strength of Acids:

Acid strength refers to the extent of dissociation of an acid when dissolved in water. Most chemists memorize the common strong acids, but you can sometimes find them printed in data booklets. You could also research its acid dissociation constant ({eq}\rm K_a {/eq}) or {eq}\rm pK_a {/eq}. A strong acid will have a {eq}\rm K_a {/eq} much larger than 1, or a {eq}\rm pK_a {/eq} that is very low (often negative).
