Sodium dithionite Thanks for the link |

Sodium dithionite Not realy, since the dithionite percipitates S when mixed with water, especially when heated. |

Safty in making large quantities of Copper Acetylide Are you planning to do Reppe chemistry, since Cu2C2 is uesed there as a catalyst |

H2O2 + NaHSO4 The H2O2 decays into O2 and H2O using the MnO2 as a catalyst. |

Thorium chloride extraction. I think so.
Btw are your mantles used?
When not, couldnt you just soak them in water sinc they are ... |

Thorium chloride extraction. In the Holleman Wiberg(best book of inorganic chemistry in austria) is written that ThO2 would react ... |

Thorium chloride extraction. Can´t you just reduce it with lets say Mg powder like:
ThO2 + 2 Mg --> Th + 2 MgO ?

Thorium chloride extraction. No, since you will form ThO2 wich is very inert.
It´s only shlightly soluble in hot conc. H2SO4.

Thermometers What are you going to do to the Hg?
[Edited on 2-1-2018 by The Austrian Scientist] |

0.1M HCl questions Yes, but to be precise you need to add 2 mL of conc. HCl.
Storage of the 0,1 M solution shouldn´ ... |

Nickel salts and compounds Ni does not disolve in HCl. You could use dilute HNO3 or ad a bit of H2O2 to the HCl to disolve it.
