Explain the effect on concentration of hydronium ions and pH of an acidic solution on dilution
Asked by manasaajit269 | 22 Jun, 2020, 10:09: PM
answered-by-expert Expert Answer

Effect on Concentration-
 
concentration depends on volume.
 
Concentration of solute= moles of solute\volume of solution
 
in case of dilution, Volume of solution increases so concentration of hydronium ions decreases.
 
 
Effect on pH-
when you are diluting any acid or base, ammount of water increases in the solution, pH of water is 7. So, pH of acid/base will shifts closer to 7 after dilution. For acid, it increases and for base, it decreases.
