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 demonstration of the proper use of a burette system for titrations; including a detailed description, instructional video, and opportunity for students to collect data to ...

Question: What’s the difference between soil pH and buffer pH? My soil has a pH of 5.1 and a buffer pH of 6.7. Answer: Soil pH is the measure of active acidity. Active acidity is soil solution ...

In this presentation, we will present a novel way of concentrating samples and performing buffer exchange using the µPULSE —TFF System. The instrument is a fully automated walk-away system that uses ...

Figure 1: Comparison of the labelling efficiency in vitro and within the E. coli cytoplasm. Figure 2: Toxicity of Cu(I) complexes inside E. coli cells. Compartment-specific pH indicators derived from ...

Buffers are an essential part of laboratory experiments in a variety of applications. Trying to calibrate the correct concentration and pH value can be a tedious, time-consuming task for scientists.
