🤓 Based on our data, we think this question is relevant for Professor Tiani's class at UNC.
We are being asked to arrange the given aqueous solutions, all at 25°C in order of decreasing acidity.
Recall that the stronger the acid, then the lower the pH. We have to determine and compare the pH for each given aqueous solution.
Arrange the following aqueous solutions, all at 25°C in order of decreasing acidity.
a. pOH = 8.05
b. 0.0023M HCl
c. pH= 5.45
d. 0.0018M KOH
