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.
a solution with a pH of 7.0 has_times _H+ than a solution of pH10.
10
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+]
1000 times more
yes
True!
Homogeneous .
None, if like me, you like your coffee black.
homogeneous
Just pure black coffee is a homogeneous mixture if it looks like its one entity (no little particles of sugar floating around, streaks of cream, etc.) basically if it looks like a solution (a mixture that seems to be made of only one thing) then it is a homogeneous mixture.
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!!
The pH of black coffee is approx. 5.
"Black" coffee is coffee without milk and sugar.
Yes coffee is black

Yes. Black coffee is a homogeneous mixture.
Black coffee is acidic with a pH of 5
Black coffee is not a solution, but is actually a mixture. Small particles of the coffee (and sometimes actual grounds) make it through the coffee filter and give it a uniform, black color.
Coffee is a homogeneous mixture (assuming it has been well-stirred), as the mixture has a uniform composition throughout. Dividing the mixture into macroscopic parts, each part will have the same composition as the original mixture.
It is not always black!
