Moreover, the earlier marine pH records are often … WebMar 2, 2024 · pH is a measure of how acidic/basic water is. The range goes from 0 to 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 …
WebWhich of the following correctly describe the pH scale? (select all that apply) - It ranges from 0 to 14 - It is a logarithmic scale - A pH above 7 represents an alkaline solution The ____ if the oceans has remained relatively constant over time because the input of salts is equal to the output. salinity WebOcean acidification is the lowering of seawater pH over time, as the ocean absorbs carbon dioxide (CO 2) from the atmosphere. The pH scale is used to measure how acidic or basic a water-based solution is. A pH value below 7 indicates an acid; and above 7 indicates a base.
WebJul 22, 2024 · The accepted pH level in a basic saltwater system is between 7.6 and 8.4, but reef tanks are more sensitive, and therefore need to be kept at the higher end of the pH scale, 8.0 to 8.4. To control or adjust pH, one …
