pH is a measure of acidity or alkalinity in a substance. Acids donate protons, bases accept protons, and chromatography techniques separate mixtures.

• pH is a scale from 0-14 to measure acidity or alkalinity

• Acids donate protons, lowering pH (0-6.9)

• Bases accept protons, raising pH (7.1-14)

• Chromatography techniques like HPLC and GC separate mixtures based on different properties

• Examples of acids: hydrochloric acid (HCl), c...read more

The Seandmeya reaction is a chemical reaction used in organic chemistry to synthesize aldehydes from alkynes.

• The Seandmeya reaction involves the hydroboration-oxidation of an alkyne to form an enol intermediate, which tautomerizes to the aldehyde.

• The reaction is often used in the synthesis of complex molecules and natural products.

• An example of the Seandmeya reaction is the conversion of 1-octyne to octanal using BH3 a...read more
