Question

the ph of wines varies from 2.8 to 3.8. 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 3.6. find the corresponding hydrogen ion concentration of the wine. (round your answer to two decimal places.) × 10 m a certain italian white wine has a ph of 2.9. find the corresponding hydrogen ion concentration of the wine. (round your answer to two decimal places.) × 10 m (b) which wine has the lower hydrogen ion concentration? california red wine italian white wine resources read it

Explanation:

Step1: Recall pH formula

The formula for pH is $pH = -\log[H^+]$, where $[H^+]$ is the hydrogen - ion concentration. We can rewrite it as $[H^+]=10^{-pH}$.

Step2: Calculate hydrogen - ion concentration for California red wine

Given $pH = 3.6$ for California red wine. Substitute into the formula: $[H^+]=10^{-3.6}\approx2.51\times 10^{-4}$ M.

Step3: Calculate hydrogen - ion concentration for Italian white wine

Given $pH = 2.9$ for Italian white wine. Substitute into the formula: $[H^+]=10^{-2.9}\approx1.26\times 10^{-3}$ M.

Step4: Compare hydrogen - ion concentrations

Since $2.51\times 10^{-4}<1.26\times 10^{-3}$, the California red wine has a lower hydrogen - ion concentration.

Answer:

California red wine has a hydrogen - ion concentration of $2.51\times 10^{-4}$ M.
Italian white wine has a hydrogen - ion concentration of $1.26\times 10^{-3}$ M.
For part (b), the answer is California red wine.
