Chemistry Notes. pH and [H + ]. pH and [H + ]. Working with the Arrhenius acid definition, we say that acids produce hydrogen ions: HX a H + + X - And bases produce hydroxide ions: XOH a X + + OH -. Water, being made up of both H + and OH - can dissociate giving us the formula:

Ionization of Water

Ionization of Water

pH. Ionization of Water. When compounds dissociate/ionize in and aqueous solution, they produce ions - hydronium ( H 3 O + ) and hydroxide ( OH - ) T hese ion concentrations can be expressed more easily as [H 3 O + ] = 1.0 x 10 - 7 M and [OH - ] = 1.0 x 10 - 7 M.

pH and pOH

pH and pOH. Ways to measure Acidity/ Basicity What is pH? What is pOH ?. What is pH?. pH = potential Hydrogen The pH scale measures how acidic or basic a substance is, is logarithmic The pH scale ranges from 0 to 14. A pH of 7 is neutral.
