PKA VALUE 🔥 | MS CHOUHAN SIR
The pKa value is one method used to indicate the strength of an acid. pKa is the negative log of the acid dissociation constant or Ka value. A lower pKa value indicates a stronger acid. That is, the lower value indicates the acid more fully dissociates in water. What is pH and pKa? The pH is a measure of the concentration of hydrogen ions in an aqueous solution. ... Essentially, pKa tells you what the pH needs to be in order for a chemical species to donate or accept a proton. The relationship between pH and pKa is described by the Henderson-Hasselbalch equation. The Weaker The Conjugate Base, The Stronger The Acid. So Any Factor Which Stabilizes The Conjugate Base Will Increase Acidity. An acid base reaction involves the donation of a proton (H+) from an acid to a base. ... The species which loses H+ is the acid. The species which gains H+ is the base. The increase in acid strength with increasing number of terminal oxygen atoms is due to both an inductive effect and increased stabilization of the conjugate base. Any inductive effect that withdraws electron density from an O–H bond increases the acidity of the compound. There are 7 strong acids: chloric acid, hydrobromic acid, hydrochloric acid, hydroiodic acid, nitric acid, perchloric acid, and sulfuric acid. Being part of the list of strong acids doesn't give any indication of how dangerous or damaging an acid is though. -------------------------------------------------------------------------------------- Join me on UNACADEMY: https://unacademy.com/@msc-0101 Join me on Facebook: / vibrantkota Join me at Telegram: https://t.me/mschouhankota Follow me on Instagram: https://instagram.com/ms_chouhan_msc_... -------------------------------------------------------------------------------------- Please like share, and subscribe to my YouTube channel. -------------------------------------------------------------------------------------- #MSCHOUHAN #IITJEE2021 #pka_value
