... 0.020 M OH− . In this case, there are two OH− for each Ca(OH)2 . We label this solution 0.010 M Ca(OH)2 , again recognizing that we are dealing with strong electrolytes and that there is essentially no undissociated Ca(OH)2 molecules in solution. This naming convention for solution concentration is ...

Qualitative Analysis of Anions
... Most of the acids and bases used are very concentrated and can cause chemical burns if spilled. Handle them with care. Wash acid or base spills off of yourself with lots of water. Small spills (a few drops) can be cleaned up with paper towels. Larger acid spills can be neutralized with baking soda, ...

corrected Amino acids and Protein
... Amino acids are building blocks of proteins. More than100 amino acids have been isolated and identified but only 25 are obtained upon hydrolysis of typical proteins. All 25 except 2 are αamino acids; the two exceptions are proline and hydroxy proline, which are imino acids. Only 20 amino acids are o ...

Acid rain
Acid rain is a rain or any other form of precipitation that is unusually acidic, meaning that it possesses elevated levels of hydrogen ions (low pH). It can have harmful effects on plants, aquatic animals and infrastructure. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide, which react with the water molecules in the atmosphere to produce acids. Governments have made efforts since the 1970s to reduce the release of sulfur dioxide into the atmosphere with positive results. Nitrogen oxides can also be produced naturally by lightning strikes and sulfur dioxide is produced by volcanic eruptions. The chemicals in acid rain can cause paint to peel, corrosion of steel structures such as bridges, and erosion of stone statues.
