But, the adhesion between the nickel plating and the steel part has been erratic. Use an ultrasonic cleaner. Does anyone out there perhaps have the original General Motors simple formulation sans inhibitors? It is another object of the invention to provide an improved ferric chloride etching solution particularly adaptable for etching surfaces of copper, nickel, and alloys of copper and nickel. DON'T mix either spent stripper or stripper rinse with anything else, or try to "trickle it in" to your waste treatment system. Various chrome-plating baths are commercially available. The resist material described is subject to some degree of chemical attack by ferric chloride solutions according to the invention; therefore, it is generally desirable when using this particular resist in the practice of the invention to remove the resist material subsequent to the etching process.

It has been shown that an excess of ferrous salt in iron-gall ink leaves permanent traces of active soluble salts not properly oxidized into inert pigments which will catalyze the slow decomposition of cellulose, especially when acidity is present. The recommended settings for various instrumental parameters may vary from one instrument to the other as well as model to model. Inject a known volume of the component of interest through the septum and again reweigh the vial. The solution should be quite colourless if much iron is present it may be faintly yellow. Solidification point is an empirical constant defined as the temperature at which the liquid phase of a substance is in approximate equilibrium with a relatively small portion of the solid phase. Calcium salts moistened with hydrochloric acid impart a transient yellowish red colour to a non-luminous flame. Dilute to the mark with water.

Many of these benefits bring to mind the question of causation or correlation. Especially stuff like heart disease and such seems rather unlikely to be cut in half, rather I suspect it is that the people that don't have sex are more likely to be obese.
