Blood is naturally slightly alkaline or basic. Here’s what that means. The pH scale measures how acidic or alkaline — basic — something is. Your body works constantly to carefully control pH levels of ...

The pH of blood refers to how acidic it is. Changes to blood pH can signal underlying medical issues, including metabolic acidosis, respiratory acidosis, metabolic alkalosis, and respiratory alkalosis ...

Your body is constantly performing a delicate balancing act that most of us never think about. While we’re busy worrying about calories and carbs, a microscopic chemistry experiment determines how ...

Identify the independent (manipulated) and dependent (responding) variables in a scientific investigation. Draw conclusions about the relationship between two variables using quantitative data.

This lab includes a theoretical explanation of how buffers work and how they are made, including a derivation of the Henderson-Hasselbalch equation. Students will use what they have learned to ...

What buffers do: Buffers limit pH changes by using a weak acid and conjugate base pair to neutralize added acids or bases through reversible reactions. Why pKa matters: A buffer’s pKa determines the ...
