In chemistry, the pH of a solution is a measure of the acidity or alkalinity of a solution. Water has a pH of 7 and, in general, acids have a pH less than 7 and alkaline solutions have a pH greater than 7. Find the pH of a solution with a hydronium ion concentration of 8.3 x 10 moles/liter.

) The acidity or alkalinity of a solution is described using the pH scale. Basically, pH (which stands for "potential of hydrogen") is a measure of how many H+ ions there are in a solution. As we saw in the previous question, the more H*s there are in a solution, the more acidic it is. The formula for calculating pH is given below: In words, pH equals the negative log base ten of the hydrogen ion concentration. Solution X has...

3. Water will spontaneously break apart as follows: H20 - H + OH This does not happen to a very large degree under normal conditions. In fact the concentration of H in water is 1 x 10" moles/liter. That is 0.0000001 moles /liter. Since one OH' is produced per Hits' concentration is the same. The solution is therefore neutral and the pH is 7. Calculate for yourself that the Log (1 x 10") is equal to 7. This will ensure...
