Moderate means between the two extreme limits. Moderately soluble means solubility between freely soluble and insoluble. (1-10 mg/100 ml)
Silver sulfide is not soluble in water. It is an insoluble compound that will not dissolve or dissociate in water to form ions.
The solubility of tyrosine varies in different solvents. It is most soluble in water, moderately soluble in alcohol, and less soluble in non-polar solvents like ether.
Almost all salts containing potassium are soluble, including KClO3 (potassium chlorate).
Silver nitrate is soluble in water but chloride and carbonate are insoluble.
Amphetamine is "Soluble in water" according to the MSDS sheet Ethyl Alcohol is easily soluble in cold water, hot water and soluble in methanol, diethyl ether, acetone.
According to the US Pharmacopeia, codeine in free base form is freely soluble in ethanol. However, codeine phosphate, common in many formulations including codeine, is only sparingly soluble in ethanol.
2-Chloropropane is moderately soluble in water due to its polar C-Cl bond, but it is more soluble in organic solvents such as alcohols and ethers. Its solubility in water is limited because the hydrocarbon portion of the molecule is nonpolar. Overall, while it can dissolve in water to some extent, it is better suited for organic solvent systems.
Lactose is a sugar that is moderately soluble in water. It dissolves better in warm water than in cold, but its solubility is lower compared to other sugars like glucose or sucrose. This means that while lactose can dissolve in water, it does not do so as readily as some other carbohydrates.
Codeine is a white crystalline solid, slightly soluble in water and soluble in organic solvents. It is used to reduce pain and to suppress coughing. A mild narcotic, hydrocodone is similar to codeine. Hydrocodone also used to relieve moderate to moderately severe pain and to control coughing.
The hypophosphorus acid is miscible with water.
Butalbital (5-allyl-5-isobutylbarbituric acid) is very slightly soluble in water at room temperature. It becomes moderately more soluble in boiling water. FYI, some people try to extract butalbital from Fioricet and other medications containing acetaminophen using water and filtration the same way opiates can be separated. This will not work with butalbital because it has approximately the same solubility in water as acetaminophen.
