Because in rock salt, the molecules are packed together and they take longer time to separate and dissolve. As for table salt the molecules are less packed together and take less time to dissolve. Think it like this. The more packed or tightly the substance/object is, the longer it will take for the object to dissolve. The less packed the object/substance is the faster it takes to dissolve. Hope this helped :)

Answer:
pH = 8.1
Explanation:
Assuming that we are at 25 degrees Celsius, pH + pOH = 14.
We can then plug in the given pOH and solve for pH:
pH + pOH = 14
pH + 5.9 = 14
pH = 14 - 5.9 = 8.1
