WebThe pH of a salt solution is determined by the relative strength of its conjugated acid-base pair. Salts can be acidic, neutral, or basic. Salts that form from a strong acid and a weak base are acid salts, like ammonium chloride (NH4Cl). Salts that form from a weak acid and a strong base are basic salts, like sodium bicarbonate (NaHCO3). Sort by: WebNow, if we know the value for K a, we can calculate the hydrogen ion concentration and therefore the pH. K a for ethanoic acid is 1.74 x 10-5 mol dm-3. Remember that we want to calculate the pH of a buffer solution containing 0.10 mol dm-3 of ethanoic acid and 0.20 mol dm-3 of sodium ethanoate. Then all you have to do is to find the pH using ...

WebIn scientific notation, for example, if the concentration of this ion is 1x10^-10 mol/L, then the pH would be 10! Therefore, you can work backwards to see that if an acid had a concentration of 1x10^2 mol/L, then its pH would be -2! so basically negative pH indicates that the acid is very strong.
