- Using a substance of ph 5 as an
example:
- Classify it as acid/base.
- What is the concentration of [H+] and [OH-].
- Give two examples of a substance with that pH.
Homework Answers
I)Any substance with pH of less than 7 is termed an acid. Hence a substance with pH 5 is an acid.
ii) pH = - log [H+] = 5
[H+] = 10^-5 M
[OH-] = 10^-14/10^-5 = 10^-9 M
iii) black coffee and bananas have pH 5

To calculate the concentration of a solution using acid–base titration data. In an acid–base titration, an acid (or base) of known concentration is added to a base (or acid) of unknown concentration until the number of moles of H+ and OH- are equal, a condition called the equivalence point. Since you know the number of moles of H+ (or OH- ) that you added, you can determine the number of moles of OH- (or H+) in the unknown solution. For...

± pH of a Strong Acid and a Strong Base pH is a logarithmic scale used to indicate the hydrogen ion concentration, [H+], of a solution: pH=−log[H+] Due to the autoionization of water, in any aqueous solution, the hydrogen ion concentration and the hydroxide ion concentration, [OH−], are related to each other by the Kw of water: Kw=[H+][OH−]=1.00×10−14 where 1.00×10−14 is the value at approximately 297 K. Based on this relation, the pH and pOHare also related to each other...

Using pH values to classify solutions as acidic, neutral, or basic is convenient. However, the basis for whether a solution is acidic, neutral, or basic is actually determined by the relative concentrations of H+and OH-in solution (represented as [H+] and [OH-]). In terms of [H+] and [OH-] (and not pH or a specific concentration), explain what makes a solution acidic, basic, or neutral.
