Som nogle af jer nok har regnet ud så er kemi ikke min stærke side :D

Sulfamidsyre (NH2SO3H) er en monohydron
syre, der anvendes som afkalkningsmiddel
i kaffemaskiner. pK; er 0,99.
Et pulverbrev indeholder 25 g, og det tænkes
opløst i en halv liter vand.

  • 1. Beregn syrens koncentration i opløsningen.
  • 2. Beregn opløsningens pH.


How? :o
