5 pH There are several ways to determine acids and bases One of them is pH [H+] is important in many chemical reactions A quick way to refer to [H+] is by pH By definition pH = -log[H+] The pH scale, like the Richter scale, describes a range of values. A ‘6’ earthquake is 10 stronger than a ‘5’ Thus, the pH scale condenses the possible values of [H+] into a 14-point scale, making it easy to say pH = 7 versus [H+] = 1 x 10–7.

PH = – log[H+] (‘-‘, ‘log’, ‘6.3’, ‘EE’, ‘(-)’, ‘5’) Answer: 4.2 If pH = 7, 4 then [H+] What? [H+] = log – 1 (-pH) (‘2nd’, ‘log’, ‘(-)’, ‘7.4’, ‘=’) 3.98 x 10–8 M
B) pH = – log [H+] = – log [1×10–7] = 7.0 c) pH = – log [H + ] = – log [2.5×10–6] = 5.60 d) pH = – log [H + ] = – log [1.3×10–4] = 3.89 e) [H+] = 10 – pH = 10–5.4 = 3.98 x 10–6 mol/l f) [H+] = 10 –pH = 10–5.72 = 1.9 x 10-6/l
It’s similar, but different POH = – log [OH-] pH + pOH = 14 [H+] [OH-] = 1 x 10–14 pH, pOH, [H+] and [OH-] a) [OH-] = 1×10–6 M b) [H+] = 2.3×10–3 M c) pH = 1.7 d) pOH = 9.2 [H+] = 1 x 10–8 M pH = 8 pOH = 6 [OH-] = 4.34 x M pH = 2.64 pOH = 11.36 [H+] = 2.0 x 10-2 M [OH-] = 5.0 x M pOH = 12.3 [H+] = 1.6 x 10-5 M pH = 4.8 [OH-] = 6.31 x M
10 Measuring pH Now that we know how to calculate the pH of a solution, how do we measure it? There are many ways to test pH Blue litmus paper (red = acid) Red litmus paper (blue = basic) pH paper (multi-colored) pH meter (7 – neutral, 7 – basic) Universal indicator (multiple colors). colored) indicators such as phenolphthalein natural indicators such as red cabbage, radish

All indicators do not change color at pH 7 Many change color over pH values When testing a sample for acidity or basicity, it is best to choose an indicator whose color change is close to pH 7, or use pH paper, or use a pH meter for a digital reading.

A base combines with H + OH from an acid to form H2O molecules It is often useful to think of H2O as the H-OH cation from a base combining with an ion from an acid to form a salt Acid + base → salt + water HCl(aq) + NaOH(aq) → NaCl(aq) + H2O(l) tro, Chemistry: Molecular Approach
It does not explain why molecular substances like NH3 dissolve in water to form basic solutions – although it does not contain OH– ions, it does not explain how some ionic compounds like Na2CO3 or Na2O dissolve in water to form basic solutions. contain OH– ions, does not explain why molecules such as CO2 dissolve in water to form acidic solutions – even though they do not contain H+ ions, this does not explain acid-base reactions that occur outside of aqueous solution,
