If excess acids are removed, PtCl 4 crystallizes from aqueous solutions in large red crystals of pentahydrate PtCl 4 ·5(H 2 O), [5] which can be dehydrated by heating to about 300 °C in a current of dry chlorine. The pentahydrate is stable and is used as the commercial form of PtCl 4. Treatment of PtCl 4 with aqueous base gives the [Pt(OH) 6 ...

β-PtCl 2 is prepared by heating chloroplatinic acid to 350 °C in air. [4] H 2 PtCl 6 → PtCl 2 + Cl 2 + 2 HCl. This method is convenient since the chloroplatinic acid is generated readily from Pt metal. Aqueous solutions of H 2 PtCl 6 can also be reduced with hydrazinium salts, but this method is more laborious than the thermal route of Kerr ...
In 2019, PTCL and Ufone were merging a number of their departments. [6] Rashid Khan, president and CEO of both Ufone and PTCL, died in December 2020. [7] In 2021, it purchased its own 4G spectrum license for US$279 million. [3] In July 2021, Ufone had around 23 million cellular subscriptions, and had a market share of 12%.
Chloroplatinic acid (also known as hexachloroplatinic acid) is an inorganic compound with the formula [H 3 O] 2 [PtCl 6](H 2 O) x (0 ≤ x ≤ 6). A red solid, it is an important commercial source of platinum, usually as an aqueous solution. Although often written in shorthand as H 2 PtCl 6, it is the hydronium (H 3 O +) salt of the ...
