Find the activity coeffi cient of H1 in a solution containing 0.010 M HCl plus 0.040 M KClO4. What is the pH of the solution

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.

the correct answer would be d. hope this !
