WebpH is the criterion used to measure the solution’s hydrogen ion concentration. It is used to determine the acidity of the solution. pH is equivalent to the negative logarithm of hydrogen ion concentration. pH = – log [H – ] If the pH value is less than 7, the solution is acidic. If the pH value is equivalent to 7, the solution is neutral. WebOct 10, 2005 · Upon evisceration, it was discovered that the frog had died due to acid ingestion. 10mL of gastric juice was found in its stomach required 7.2mL of 0.1 M NaOh for neutralization. Calculate the pH of its gastric juice. I'm confused, how would I approach this problem. Well first you might want to find the pH of the NaOH solution.
