Answer: 3.2
Explanation:
pH is the measure of acidity or alkalinity of a solution.
pH is calculated by taking negative logarithm of hydrogen ion concentration.
![pH=-\log [H_3O^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%20%5BH_3O%5E%2B%5D)
Thus as pH and 
are inversely related, a solution having lower pH will have more amount of concentration. And a solution having more pH will have less amount of concentration.
Thus the solution with lowest pH of 3.2 will have highest hydronium ion concentration.
THe loss of 2 protons and 2 neutrons (also called a helium nucleus) is defined as alpha decay.
