Discover what acidic, basic, and neutral means. Learn what makes something acidic, what number is neutral on the pH scale and the pH of acidic...
Indicate whether the following substance is acidic, basic, or neutral. Soft drink, pH 2.8 pH: One can easily state conclusion regarding a chemical substance's nature (if its neutral/acidic/basic) on the basis of its known pH value. Some pH values for acidic sub...
What are normal levels of water sulfates? What is the charge on alkaline earth metal ions? What is a hydrogen ion gradient? What are examples of acidic and basic salts? What ions form when water dissociates? Classify each of the following drugs as either acidic, basic, or neutral. Briefly...
our bodies drop or deposit acid and alkaline minerals from the bones, soft tissues, body fluids (blood, saliva, and urine). Your pH levels are usually more acidic in the morning, fluctuating during the day.
From my research I can conclude that the enzyme Lactase works best at a neutral pH level of 7 and worst at acidic pH levels of 2 and basic pH levels of 10 as shown in Figures 1 and 2. This is because Lactase is a digestive enzyme that catalyzes the breakdown of lactose, a sugar in...
So how can organisms whose bodies require a near-neutral pH ingest acidic and basic substances (a human drinking orange juice, for example) and survive? Buffers are the key. Buffers readily absorb excess H+ or OH–, keeping the pH of the body carefully maintained in the narrow range ...
Because of this free proton-to-buffer component ratio, cellular pH will be intrinsically buffered by all weakly acidic and basic components of the cell (Table 1). To understand biological function, it is more useful to know the relative protonation of all weakly acidic or basic molecules in ...

The 580/640 nm emission ratio of the SNARF-1 dextrans increases (Probes Useful at Near-Neutral pH—Section 20.2). The fluorescein, BCECF and SNARF dextrans are useful for detecting translocation into compartments that have an acidic pH; however, the relative insensitivity of their fluore...
It is a measurement of how acidic or basic the water is, and is based on a scale from 0-14, with a pH reading of 7 being neutral. Anything below 7 is considered acidic, while anything above 7 is considered basic or alkaline. For swimming pools, the ideal pH range is 7.4-7.6 (7.2...
