chemistry

when silver nitrate solution is spilled on the skin, a pale brown colour is formed.

it is not easy to clean it. and it is toxic too.

when silver nitrate solution is spilled on the clothing, the stain will not fade out unless

you use bleaching solution.

silver ion接觸到皮膚就會有灰色斑點出現,是洗不掉,要等到新陳代謝脫皮先甩到。而且本身亦是有毒。如果濺左上衫上面就更加洗唔甩。
