[1] [3] PTCL provides telephone and internet services nationwide and is the backbone for the country's telecommunication infrastructure. The corporation manages and operates around 2000 telephone exchanges across the country ...
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 ...
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] 2− ion. With methyl Grignard reagents followed by partial hydrolysis, PtCl 4 converts to the cuboidal cluster [Pt(CH 3) 3 (OH)] 4. [6] Upon heating PtCl 4 evolves chlorine to give PtCl 2: PtCl 4 → PtCl 2 + Cl 2
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 ...
The Telecommunications Ordinance of 1994 created the Pakistan Telecommunication Authority (PTA), Pakistan's first independent telecommunications regulator, and the Pakistan Telecommunication Company Ltd (PTCL), a state-owned monopoly. [1] Due to a lack of competition, local telephone call rates were high and international call rates were even ...
