Question

If the pH of a wine is too high, say, 4.0 or above, the wine becomes unstable and has a flat taste. (a) A certain California red wine has a pH of 3.5, and a certain Italian white wine has a pH of 2.9. Find the corresponding hydrogen ion concentrations of the two wines. (Enter your answers to five decimal places.)

Answer 1

Answer:

The Californian red wine (pH 3.5) has a hydrogen concentration of 0.00032M

The italian white wine (pH 2.9) has a hydrogen concentration of 0.00126 M

Explanation:

Step 1: Data given

Wine 1 has a pH of 3.5

Wine 2 has a pH of 2.9

Wine 2 is more acid so should have more hydrogen ions

Step 2: Calculate hydrogen concentration

pH = -log [H+]

Wine 1: pH = 3.5 = -log[H+]

[H] = 10 ^-3.5 M = 0.00032 M

Wine 2: pH =2.9 = -log[H+]

[H+] = 10^-2.9 = 0.00126 M

The Californian red wine (pH 3.5) has a hydrogen concentration of 0.00032M

The italian white wine (pH 2.9) has a hydrogen concentration of 0.00126 M

The italian white wine has a higher concentration of hydrogen ions, what means it's more acid than the californian red wine.
