Scientists investigating a proposed way to remove carbon dioxide from the atmosphere using seawater have found that adding too much alkalinity to neutralize acids can trigger chemical reactions that ...

When we talk about carbon removal, the conversation often feels like science fiction. Machines that suck CO₂ directly from the air, forests genetically engineered to grow faster, mineral powders ...

To mitigate climate change, human-made carbon dioxide (CO2) emissions must be reduced as quickly and drastically as possible. Additionally, some of the CO2 already emitted needs to be safely removed ...

As power plants across the country plan to close ash ponds, the first discharge limit to consider is pH. National standards require all wastewater discharges to comply with a pH between 6 and 9 ...

The world’s oceans stow vast amounts of carbon dioxide. Now, a growing group of scientists and companies say they’ve found a way to increase that storage capacity by tweaking ocean water chemistry.

The pH scale measures the acidity or alkalinity of a substance, ranging from 0 to 14, with values below 7 representing acidity, above 7 representing alkalinity, and 7 representing neutrality.
