Phenolphthalein would not be an appropriate indicator to use to determine the Ka1 of phosphoric acid Why What indicator would be appropriate?
Phenolphthalein is not suitable for determining the Ka1 of phosphoric acid as it changes color at a pH around 8-10 while the Ka1 dissociation of phosphoric acid occurs at a much lower pH of around 2. A suitable indicator for determining the Ka1 of phosphoric acid would be methyl orange, which changes color in the pH range of 3.1-4.4, closer to the pH range of the dissociation of the first hydrogen ion from phosphoric acid.
If stomach acid has a PH of 1 and a person took a tums tablet which raised the PH to 3 how much was the increase in PH?
The increase in pH would be 2, as going from a pH of 1 to a pH of 3 represents a change of 2 pH units.
What is the pH level of head and shoulders shampoo?
1. First we took some samples out of the shampoo bottles. 2. Place the pH meter into the sample of shampoo and held it there for about a minute or until the reading stayed constant. you'll get the following results Exact for Normal Hair- 8.52 (highest) Vive Smooth Intense- 6.29 Herbal Essences- 6.08 Head and Shoulders- 6.00 Dove Beautifully Clean- 5.48 Garnier Fructis- 3.41 (lowest)
Would a substance with pH value of 2 be very acidic or very basic?
A substance with a pH value of 2 would be considered very acidic, as pH values below 7 indicate acidity.
Where would you find very acidic things on the pH scale?
You would find very acidic things with a low pH value (0-6) on the pH scale. Examples include stomach acid (pH 1-3), vinegar (pH 2-3), and lemon juice (pH 2-3).
What would the pH of stomach acid be?
2 pH is the answer

What substance would do the best job of cleaning pots and pans 7 2 4or 8?
it would be a substance with a pH of 13
What is a substance that is slightly acidic would have a pH of?
2

If you mix equal amounts of solution A with a pH of 2 and solution B with a pH of 8 is it acidic or basic?
A solution with a pH of 2 is strongly acidic. Remember, 7 is neutral, anything below 7 is acid, anything above 7 is basic or alkaline.
Does an acid have pH of about 6?
No, an acid typically has a pH below 7. A pH of 6 is slightly acidic, but a stronger acid would have a pH closer to 1 or 2.
What would happen if you add a drop of buffer solution at PH 2 into a pool filled with pure PH 7 water?
A drop is insignificant compared to an entire pool, so no change would be observed. However, if the volume of the buffer was comparable to the volume of the pool, pH would change to be somewhere between 2 and 7.
