Furthermore, the specific gravity of the plating solution may be so high to cause crystallization of some of the metal chelates present therein. Suitable metal chelates include those in which the metal portion is selected from the group consisting of indium, nickel, cobalt, zinc or cadmium.
Specific Gravity or relative gravity is a dimensionless quantity that is defined as the ratio of the density of a substance to the density of the water at a specified temperature and is expressed as. It is common to use the density of water at 4 o C as a reference point as water at …
The prior art for measuring the specific gravity of a fluid has essentially been by employing a hydrometer which directly determines by a flotation measurement the specific gravity. Where the corrosive environment of plating solutions is involved, hydrometers can become encrusted with mineral salts and therefore their buoyancy change, with a ...
Depending on the concentration, the specific gravity of a nickel sulfamate bath is probably about 1.15 to 1.25. The boiling point is higher than 212 because of the dissolved salt. You could estimate the surface tension as 50 dyne/cm, and maybe extrapolate viscosity from that.

In this study, density, specific gravity, and baricity of local anesthetic solutions at body temperature were determined volumetrically to five significant figures. Standard solutions of 2% lidocaine, 0.5% and 0.75% bupivacaine, and 0.9% sodium chloride were tested. Bupivacaine, 0.75%-water dilutions and tetracaine, 0.2%, in water were also ...
Specific Gravity Formula. Specific Gravity gives information about the weight and density of the object. It can be calculated by comparing the weight, mass and density of the given object with water of the same amount at 4 0 C. Specific gravity is a unitless measurement. The density of water is 1000 Kg/m 3.
bailed volume, and is typically controlled through specific gravity. Deposit Properties Plating Rate/Deposit Thickness Not strictly a deposit property, plating rate is a key charac-teristic of an electroless copper plating bath. Plating rate and useful range of deposit thickness dictate the specific applica-bility of a formulation.
