What is the n factor of HCL in reaction with K2Cr2O7? - Quor

36.5 grams of hydrochloric acid (HCl) is a 1 N (one normal) solution of HCl. A normal is one gram equivalent of a solute per liter of solution. Since hydrochloric acid is a strong acid that dissociates completely in water, a 1 N solution of HCl would also be 1 N for H + or Cl-ions for acid-base reactions CHROMATE - DICHROMATE EQUILIBRIUM • Addition of NaOH and HCl • Addition of Barium Nitrate pieferrer/Chem3.SY2013-2014 2.

You are absolutely correct. Adding $\ce{HCl}$ adds protons to the mix, which you can imagine as applying pressure on the right-hand side, which means that the reaction will shift backwards slightly and the acetate concentration will decrease. For $\ce{NaOH}$, you also need to consider the underlying equation: $$\ce{H2O <=> H+ + OH-}$
