1. C. Turn Litmus blue. Acids typically turn litmus paper red, not blue. that's what bases do. The other options all describe acid properties: acids produce H+ ions in water, taste sour, react with active metals to release hydrogen gas, and react with carbonates and bicarbonates to produce CO2. Turning litmus blue is just not something acids do, so it stands out as the exception.4. B. Basic pH is a measure of how acidic or basic a solution is. A pH of 7 is neutral, below 7 is acidic, and above 7 is basic. Since pancreatic juice has a pH of 8.0, which is above 7, it's basic. This makes sense, given that pancreatic juice helps neutralize stomach acid in the digestive process.5. D. resists changes in pH caused by the addition of small amounts of strong acids or bases.Buffers are solutions that help maintain a relatively stable pH even when small amounts of acid or base are added. They typically consist of a weak acid and its conjugate base (often provided by a salt). Buffers don't necessarily maintain the pH at 7.0 (neutral), but rather at a specific pH value depending on their composition. And they definitely don't require a strong acid - weak acids and their conjugates are key! So, resisting pH changes is the hallmark of a buffer.6. The normal pH of arterial blood plasma ranges between 7.35 and 7.45. 7. Acidosis. This is a condition where the blood becomes too acidic, and it can be caused by various factors such as respiratory or metabolic issues.8. Alkalosis. This is a condition where the blood becomes too basic or alkaline, which can be caused by factors like hyperventilation, excessive vomiting, or certain medications.9. The pH of intracellular and extracellular fluids in mammals typically ranges between 6.8 and 7.4, with slight variations depending on the specific fluid and location.10. 10. A. This statement is true.pHydrion paper, also known as pH paper or pH indicator strips, is a simple tool for estimating the pH of a solution. You dip the paper into the solution, and the resulting color change is compared to a reference chart to determine the pH.
