Behavior of an acid in a water solution?
Answers
Answer:
Acids and bases dissolve in water and, because they increase the concentration of either protons or hydroxide ions, they suppress water self-ionization.
For any acid, Ka is the equilibrium constant for the acid dissociation reaction in water. See this web page for a list of Ka values at room temperature. Note that both A- and H+ are surrounded and stabilized by water molecules. We could also write these as [A(H2O)x]-, [H(H2O)x]+ or A(aq)-, H(aq)+.
pH and pOH are frequently used to describe solutions of acids and bases in water. In pure water, the concentration of solvated protons equals the concentration of solvated hydroxide anions and the pH is 7. Acidic solutions have a lower pH while basic solutions have a higher one.
This assembly was composed of three estates – the clergy, nobility and commoners – who had the power to decide on the levying of new taxes and to undertake reforms in the country. The opening of the Estates General, on 5 May 1789 in Versailles, also marked the start of the French Revolution.
