FALSE. It is 100 times more acidic and not 1000 times.
PH 4 is more acidic than PH 6. But how many times is the answer to find out.
PH = -log 10 [ H+] . Therefore [H+ ] = 10 -PH
For PH = 4, [H+] = 10 -4 and for PH = 6, [H+ ] = 10 -6
10 -6 x 100 = 10 -4 therefore PH 4 is 100 times more acidic than PH 6.

pH of 6 = concentration of H+ of 10-6or 0.000001
pH of 5 = concentration of H+ of 10-5 or 0.00001
remember, pH = -log [H+]

How do you neutralize pepper?
white or black pepper can be neutralized in some sauces with coffee, for example a white wine cream sauce (or just about any cream sauce) with too much white pepper can be repaired with a cup of black coffee without changing the color or consistency of the sauce. Please note it must be liquid coffee not coffee that has not been brewed, not coffee grounds or instant without the water, and it makes no difference if it is decaf!!
