A. Mass B. e/m ratio C. Isotopes D. None of These Mass spectroscopy primarily provides information about the ratio of the charge (e) of an ion to its mass (m), known as the e/m ratio. This technique is commonly used to identify compounds, determine their molecular structure, and measure the isotopic composition of elements. While … Read more

A. Bendict solution B. Fehling solution C. Tollens reagent D. None of These Tollens’ reagent, also known as silver mirror test, is a chemical test used to differentiate between aldehydes and ketones. Aldehydes are capable of undergoing oxidation to carboxylic acids, while ketones cannot. Tollens’ reagent, which consists of silver nitrate, ammonia, and sodium hydroxide, … Read more

A. greater than true solution B. greater than suspension C. In b/w true solution & suspension D. None of These Colloidal particles have sizes that are larger than individual molecules found in true solutions but smaller than the particles in suspensions. This puts colloidal particles in an intermediate size range between true solutions and suspensions. … Read more
