@Mr Doctor we can even use inverted funnel mehod to prevent backflow. |

Hg does not react readily with H2SO4, its slow usually. Ooh, but this process is elegant. |

Compounds that reflect more than 1 color?
Can you elobarate it? Is the colour change angle related, then Styro pyro has a video related to it. |

Credits to @unionised for HF method, it works. |

Amature chemistry channel has a vedio dirt to Si check it. Purity can be tested using HF. |
