A cup of black coffee at pH 5 has 10 timess the concentration of H plus ions than peas at pH 6True or false?
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.
What else can I help you with?
The pH of a cup of black coffee is 5 while the pH of glass of tomato juice is 4. Comparing the pH of the two liquids the tomato juice has H plus than the coffee.?
The pH scale measures the concentration of hydrogen ions (H⁺) in a solution, with lower pH values indicating higher acidity. Since tomato juice has a pH of 4 and black coffee has a pH of 5, this means that the tomato juice has a higher concentration of H⁺ ions than the coffee. Specifically, for every one unit decrease in pH, the hydrogen ion concentration increases by a factor of ten, indicating that tomato juice is ten times more acidic than coffee.
Is black coffee homogeneous or heterogeneous?
Black coffee is a homogeneous mixture. This means that it has a uniform composition throughout, with the coffee particles evenly distributed in the liquid, giving it a consistent appearance and properties.
What kind of mixture is freshly-brewed black coffee?

Is black coffee a homogeneous or heterogeneous mixture?
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.
What is the OH- ion concentration of the black coffee?
The pH of black coffee is approx. 5.
What are the differences between green coffee and black coffee?
Green coffee refers to unroasted coffee beans, while black coffee is made from roasted coffee beans. Green coffee has a higher concentration of chlorogenic acid, which is believed to have health benefits. Black coffee has a stronger flavor and aroma due to the roasting process.

Is black coffee base or acid?
Black coffee is acidic with a pH of 5
Is a black coffee a solution?
