The signs of REM sleep (muscle paralysis, EEG desynchrony, eye movements) occur in mammals. Did sleep evolve to keep our ancestors away from predators? Indus Dolphins sleep even though it's dangerous. These dolphins exist in muddy water and through natural selection have become blind because it served no purpose. Why then do they still sleep?
Sweat chloride measurements are used in the laboratory diagnosis of cystic fibrosis. Chloride Titration. The ChloroChek Chloridometer is a coulometric titrator designed to determine chloride ion concentrations in sweat samples with just 10 microliters of sweat. It displays the concentration directly in mmol/L Cl-. The sweat sample is added to an acid buffer/stabilizer working solution.
To prove that the solution is gold chloride simply requires proof that the cation is gold and the anion is chloride. The gold cation can be measured using atomic absorption/emission techniques or by using an ion selective electrode (ISE). Either test requires equipment available in many testing laboratories.old hydroxide is a gold salt which is not water soluble, making the claim scientifically impossible! For more details on ionic solubility see Solubility Rules. The chloride test described below demonstrates that products claimed to be ionic gold and gold hydroxide are really gold chloride.
