It turns the solution into pink colour
The formula for pH is pH = -log[H+]. The formula for slope is m = (y2 -y1)/(x2 - x1)
pH = pKa + log([A-]/[HA])
pH + pOH =14
Depending on its concentration you can calculate it by this formula: pH = -log[H3O+]
pH is the negative log of the hydronium ion concentration. It seems a little grandiose to call this a "formula", but here you go: pH = -log[H3O+]
pH=-log(H+)
S=ph+2b
w=ph
pH = - log [H3O+]. It is the negative logarithm of the hydronium ion concentration.
Molecular formula is C2H6O2 Maybe pH is 7. I measure the PH of ethylene glycol myself with az 8686 PH meter. The number that i saw was 8. I thinck its because of hydroxyl group(OH) in its Molecular formula(HOCH2CH2OH=C2H6O2).
