) 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...
