Question

What is the pH of a 0.050 M concentration of the strong acid HI?

PLEASE HELP ME FIND THE ANSWER I AM LOOKING TO LEARN HOW TO DO THIS

Answer 1

@Nurali @Frostbite @blues @thomaster @radar Can one of you please show me how to do this?

Answer 2

For a strong acid we assume it fully dissociates and use the definition of pH:
\[\LARGE pH=-\log \left( \left[ H ^{+} \right] \right)\]

Answer 3

In order words we assume the following reaction happens to the end:
\[\Large \sf IH + H _{2}O \to H _{3}O ^{+}+I ^{-}\]

Answer 4

Just put into the calculator:
\[\Large pH=-\log( 0.050)=\]
