Part L: pH Scale Calculations 4 points

What is the pH and pOH of the following solutions:

pOH = 14.00 – pH K_w = 1.00 x 10^-14 = [H₃O¹⁺][OH^1-]

(1) 0.000675 M HCl

(2) 0.0025 M Ca(OH)₂

(3) The pH of blood ranges from 7.35 to 7.45; calculate the [H₃O¹⁺] of 7.35 and 7.45:

(4) A ammonia cleaner has a pH of 11.00. What is the [H₃O¹⁺] and [OH ^1-]?
