Use the formulas for pH and pOH to perform the following calculations. 4. 5. What is the pH of 6.6 × 10-4M HCl? 6. What is the pH of 1.5 × 10-3M NaOH? 7. A solution of HNO3 has a pH of 4.5. What is the molarity of HNO3? 8. What is the molarity of KOH in a sol...
PH And pOH. Water Water autoionizes H 2 O + H 2 O H 3 O+ + OH- Hydrogen ion concentration determines the acidity of the solution Kc = [H3O+][OH-] ionization. pH: The negative of the common logarithm of the hydronium ion concentration [H 3 O + ] ◦ pH stands for the ...
pH pH In any solution the H3O+ and OH- concentration is always very small. pH- method of representing the H3O+ concentration in a solution. pH = -log [H3O+] So the pH of water is… pH = - log 1 x10-7 pH = 7 Anything with a pH below 7 is acidic, above 7 is basic. pOH p...
PH. Ionization of Water When compounds dissociate/ionize in an aqueous solution, they produce ions - hydronium (H 3 O + ) and hydroxide (OH - ) These. Acids, Bases, and pH. Acids and Bases Bundle 4: Water. Equilibrium of Water Pure water contains very small concentrations of ...
