When concentrated Sulfuric Acid and water are mixed, a tremendous amount of heat is released due to ionization of the acid. For instance, adding 1 volume of concentrated Sulfuric Acid to an equal volume of water (both at 25°C) results in a temperature rise to over 135°C. Therefore, the acid should always be diluted by adding it to the water. If the water is added to the acid, spattering could result which creates a hazardous situation and the possibility for severe chemical burns. The use of a 1 + 1 dilution of Sulfuric Acid with water (50% Sulfuric Acid, Group No. 8180) offers a much safer alternative in many instances when the use of Sulfuric Acid is required. For example, when 1 volume of concentrated Sulfuric Acid is added to 3 volumes of water, the temperature rises from 25°C to over 90°C. When the same solution is made by diluting 1 volume of 50% Sulfuric Acid with 1 volume of water, the temperature rises to less than 50°C.

Preventing Silver Nitrate stains on your skin

Here is a neat trick :::
  1 - Dissolve 2 teaspoons of common table salt in 1 Cup of warm water.
  2 - Place this Salt solution close by where you will be working with Silver Nitrate solutions.
Then, if you spill Silver Nitrate solution on your skin, do this:
  1 - Stop what you are doing.
  2 - Rub the Salt solution completely onto your skin, where you think the Silver Nitrate spilled.
  3 - Rub HARD, get the Salt solution as deeply into your skin as you can. You can use a paper towel.
  4 - Work quickly - you have about 10 seconds!
  5 - After a minute or so, rinse off the Salt solution in plain tap water.   If you do this promptly, the Silver Nitrate will convert to Silver Chloride,  and your skin will not darken when you later go out into the sunlight!
