Since acid rain can kill aquatic animals, weaken trees and dissolve stone, it seems like it could also scald or burn humans. But it doesn't affect people in the same way as it does fish or plants. Acid rain feels the same as regular rain -- it's even safe to swim in an acidic ...

Acids and alkalis are simply chemicals that dissolve in water to form ions (atoms with too many or too few electrons). An acid dissolves in water to form positively charged hydrogen ions (H+), with a strong acid forming more hydrogen ions than a weak one. An alkali (or base) dissolves...
If we dump hydrochloric acid onto the entire volume of nitric acid at once—all these nasty products are liberated immediately and potentially explosively. If instead, we slowly add the nitric acid to the hydrochloric acid, the reaction proceeds gently. Excess heat is allowed to dissipate, and t...
However, it doesn't dissolve as quickly as table salt, so it's better to use a finer salt when baking. When replacing table salt with kosher salt in a recipe, you usually need to double the amount because the larger kosher salt crystals take up more space. Kosher salt is not iodized....
The experiments A1–A3 demonstrate that low pH water with acetic acid (pH = 3.93–3.98) can dissolve calcite at 20 °C. As the water salinity and the Ca2+ concentration in water increase, the dissolution capacity of the acidic water decreases dramatically. Even with a high water/rock volume...
Coke:The acid of the coke will dissolve any sludge attached to your pipelines, although it may look like waste. Leave the soda on the drains for several minutes before pouring warm water on them. Enzyme cleaner:To eliminate blocks in your drain, you can also utilize eco-friendly enzymes. ...
The reason those shells don't dissolve back into calcium and carbonate as soon as they're built is that ocean water is already holding as much calcium and carbonate as it can, so the mineral forms much more easily than it dissolves.那些贝壳之所以没有一建成就重新溶解成钙和碳酸盐，是因为海水...
Purchase at least 1 lb. of citric acid crystals, sometimes sold as "Sour Salt," from your local gourmet food store. Boil 1 or 2 pints of distilled water for every pound of citric acid you plan to dissolve, depending on how strong or weak you want your solution. ...
clean it every 1 to 2 months. Cleaning a dishwasher is simple: just remove any dishes and run a cycle, using a natural cleaner like white vinegar, baking soda, or lemon juice. As an alternative, put unsweetened lemonade mix in the detergent dispenser; the citric acid cuts through grease ...
