Apr 03, 2020 Most fruit colors are phenolic compounds, and many are pH sensitive. I understand that neutral beverage spirits tend toward a pH ~4 (acidic), and certainly mixed-drinks will be acidic, so this generally tends to push the anthocyanin class of colorants toward pink/red and away from blue/purple. You may need to control pH to acheive good color ...

Now let's summarize the video. In this video we saw that salts could be acidic, basic, or neutral in nature. And the nature depends on the nature of the parent acid and base. We saw that what will be the nature of salt if the acid and base both are strong, and what will be the nature if one of them is strong and the other is weak.
