Donner la concentration en ions H3O+ de chacune de ses solutions :

Solution 1 : ph = 13
Solution 2 : ph = 1,64
Solution 3 : ph = 7,35
Solution 4 : ph = 2,40
Solution 5 : ph = 12,80

Merci de votre aide

Réponse :

solution 1: 10^-13 mol/L

solution 2: 10^-1.64 mol/L

solution 3: 10^-7.35 mol/L

solution 4: 10^-2.40 mol/L

solution 5: 10^12.80 mol/L

Explications :

pH = -log[H3O+] <=> [H3O+] = 10^-pH
