Calcula el pH de las siguientes sustancias formadas durante una erupción volcánica: • La lluvia acida si la [H+] es de 1.9 x 10-5
• El ácido sulfuroso si [H+] = 0.10
• El ácido nítrico si [H+] = 0.11

Calculate the pH of the following substances formed during a volcanic eruption:

• Acid rain if the [H +] is 1.9 x 10-5

• Sulfurous acid if [H +] = 0.10

• Nitric acid if [H +] = 0.11

pH is the degree of acidity of a solution that depends on the concentration of H⁺ ions. The greater the value the more acidic the solution and the smaller the pH.  

pH = - log [H⁺]  

the answer is c.the valence of the atoms combine .
