Palladium Print | Periodic Table ]

Location:  Group 10, Period 5
Atomic Weight:  106.42
Coordination Number:  6
Chemical Form in Solution:  Pd(H2O)62+

Storage & Handling:  Keep tightly sealed when not in use. Store and use at 20 ± 4°C. Do not pipet from container. Do not return portions removed for pipetting to container.

Chemical Compatibility:  Stable in HCl, HNO3, H2SO4, HF, and H3PO4. Avoid basic media. Stable with most metals and inorganic anions in acidic media. Avoid contact with water soluble organics such as aldehydes since Pd2+ is easily reduced.

Stability:  2-100 ppb levels. 2 ppb Pd is stable for 1 day in 1% HNO3 / LDPE container. 10 ppb is stable for 3 days in 1% HNO3 / LDPE container. 100 ppb is stable for ≥ 5 months in 1% HNO3 / LDPE container. 1-10,000 ppm solutions chemically stable for years in 1-5% HNO3 / LDPE container.

Pd Containing Samples (Preparation & Solution):  Metal (soluble in HNO3 or aqua regia); Oxides (soluble in HCl); Ores (dissolve in HCl / HNO3).
