Answer:
Explanation:
From the sorensen equation; pH = -Log[H+]
2.7 = -Log[H+]
H+ = 10^-2.7
H+ = 0.001995M = Hydrogen ion concentration
Basically, the more the charges, the higher the hydrogen ion concentration stand vice versa. +2 has the highest concentration.
Its leading to contaminated drinking water.
I think answer should be the last option I hope this helps let me know if it’s correct thanks
Tarnish is Ag2S-silver sulfide and the oxidation state of silver is +1
