  1. I made an Apple Tart in my new Carbon Steel Skillet. 🤢

  2. Just looked up the pKa of triflic acid and I had forgotten how insane it is (-14.7!!!) and would not have estimated that low based on sulfuric acid having a pKa of -2.8. Like, acetic to trilfluoroacetic only drops by 4.2 pKa unit. Holy hell is that a strong acid!

  3. Marine ecosystems: Human activities have pushed Earth beyond its Safe Operating Space.

    "World’s oceans fail key health check as acidity crosses critical threshold for marine life. The world’s oceans have failed a key planetary health check for the first time, primarily due to the burning of fossil fuels, a report has shown. Scientists call for renewed global effort to curb fossil fuels as seven of nine planetary boundaries now transgressed."

  4. Facing rising #temperatures, a spike in #acidity driven by an influx of #carbon, mass habitat destruction, and inescapable pollution, the world's #oceans haven't had it easy. But in an ominously literal sense, the situation may be even darker than we realized. New research indicates that more than a fifth of the global ocean has darkened over the past two decades, with the depths that #sunlight can penetrate significantly retreating. onlinelibrary.wiley.com/doi/10 #climatecrisis #oceans #globalheating

  5. Marine extreme events such as heatwaves, #ocean #acidity extremes and low #oxygen extremes can pose a substantial threat to marine organisms and #ecosystems.

    From 1961 to 2020, extreme events have become more intense, longer, and occupy more volume, driven by the trends in ocean warming and #acidification.

    Triple extreme events are confined to the tropics and the North Pacific and tend to be associated with ENSO.

  6. #WeekendReading: Vandeginste et al., on the role of #acidity in controlling diagenetic processes, and specifically how ions with a stronger hydration enthalpy correlate with a shorter #dolomitization induction time.

  7. @marksquires Apparently Madeira, like Santorini, has very little potassium in its soils, which is one reason the wines are so high in acidity. #volcanic #wine #acidity

  8. @pthane
    Some varieties that tend to lower acidity include Viognier, Gewurztraminer, Treixadura and Auxerrois (white); Grenache and Dolcetto (red). But relative acidity is still largely a function of ripeness at harvest and winemaking practices. And sometimes producers will acidify their wine, especially at lower price points. But maybe look for white blends from the south of France that are mostly Viognier and Grenache Blanc. #acidity in #wine

    First, do not believe what you read on-line about acidity: a lot of those sources are just plain wrong.
    Second, wine is an acidic beverage. The differences in acidity between wines is only relative.
    Third, riper wines from warmer climates tend to be lower in acid.
    Fourth, wines that have gone through malo-lactic conversion, ie most reds and some whites, will be lower in acidity as a result.
    Fifth, some varieties tend to give wines that are lower in acidity. See comment. #acidity #wine

  10. ⭐️ Malolactic fermentation affects wine’s texture and flavor, and letting it roll (or not) depends on tradition, fashion, chemistry, and more. My new Wine Science piece for Terroir Review tackles this magnificent microbial process. Enjoy! ⭐️

  11. Here’s the first in my new series on wine science topics, which tackles acidity, volatile acidity, and wine’s essential refreshment.

  12. Definitely. #Bottle #age: it's not just for red #wines, #fortified wines, sweet wines, or whites with high #acidity. Those things just make it easier to get away with. #Marsanne #Roussanne #Semillon (more examples?)

  13. #Aerosols in indoor air can vary in #acidity & the #acidity determines how long viruses remain infectious in the air. New research study from ETH Zurich, EPFL and University of Zurich shows how the pH of #aerosol particles changes in the seconds and hours after #exhalation under different #environmental #conditions. It also shows how this affects the #viruses contained in the #particles. The study appears in the journal Environmental Science & Technology. #Flu #Covid futurity.org/aerosols-acidity-

  14. What you don't know can in fact kill you: Food preservation and Botulism poisoning

    Why many canned goods have a slightly burnt taste, and why salt and acidity are so crucial to preservation.
