D Question 4 4 pts The measure of the acidity of a liquid is called the pH of the liquid. It is proportional to the base-10 logarithm of the inverse of the amount of hydrogen ions in the liquid Z. Based on the above description ONLY, choose a formula that correctly represents the relationship between the amount I of hydrogen ions in this liquid and the pH of liquid measured by . Note that k is a constant. O I=X^k 1=kx O 1=k(10^x) O I=k log x O !=kx^
