  • I am carrying out a reaction using ethyl chloroacetate, potassium carbonate in acetone for a compound containing − N H " style="position: relative;" tabindex="0" id="MathJax-Element-2-Frame" class="MathJax" ? N H ? N H group. So, the substitution will be at − N H " style="posi...
  • They seem all correct to me, is there any reason why one reaction would happen over the other(s)? K X 2 C O X 3 + 2 H C l ⟶ 2 K C l + H X 2 C O X 3 K X 2 C O X 3 + 2 H C l ⟶ 2 K C l + H X 2 O + C O X 2 K X 2 C O X 3 + H C l ⟶ K H C O X 3 + H X 2 O " style="text-alig...
  • Context: In the process of trying to calibrate a number of hygrometers, with Sensirion MEMS electronic sensors, I came across the method of using wet salt: an airtight container will stabilize at a predictable relative humidity over time, given a particular salt and temperature. For a list of salts...
  • In our village, lots of ash is produced which is thrown off. I want to extract pure potassium carbonate from that ash. I am able to extract the potassium compound and a soluble compound by recrystallizing and evaporating but I found impurities. The first test I performed is electrolysis. This test ...
