Your answer
Pure water has a pH of 7, the point
at which the concentrations of
hydrogen ions and hydroxide ions
are equal and water is considered
to have neutral pH. If an acid
is added to water, the pH value
because the acid releases
goes up above 7 ;
hydrogen ions
goes down below 7;
hydrogen ions
goes up above 7;
hydroxide ions
goes down below 7 ;
hydroxide ions
Is drinking alkaline water good for you?

Solution A is neutral, with a pH of 7. Solution B is slightly alkaline, with a pH above 7. Two beakers are filled with of each solution (one for each solution). A phosphate buffer was added to it and CO2 was blown into it until there was a change of color meaning a change in pH. (this experiment is to see how the CO2 from the lungs can cause a pH change in water) Why does it take so long for the solutions to change color? Relate your answer to the equation (H2O + CO2 ⇌ H2CO3 ⇌ HCO3- + H+ ) and to the presence of the buffer.arrow_forwardLemon juice has a pH around 2.5. Milk has a pH around 6.5-7.
