Blog post - What is pH? Test the Rainbow

Understanding pH measurements and the pH scale is vital, not only for chemistry but across many disciplines - medicine, agricultural science, oceanography, water treatment, food science, biochemistry, chemical engineering and many more.

But getting students to understand the fundamentals of pH is often a struggle. But with some 0.1 M HCl, universal indicator and a low cost Wireless pH Sensor we think we have an activity that will help students grasp the concept in a fun and colorful way.

Blog Post - Concentrate on the Conductivity

Help students gain a greater depth of understanding about solution concentrations by having them make and test their own solutions.

A bit of food coloring and our new Wireless Conductivity Sensor provide visual cues and quantitative data respectively, creating a full solution to help them concentrate on concentration.

Blog Post: Titrations are pHun!

Properties of acids, bases and the pH scale are core concepts in any chemistry class. After your students understand the basics, it is important for them to be able to quantify reactions involving acids and bases with a titration.

A classic experiment is to determine the concentration of HCl(aq) by reacting it with 0.1 M NaOH(aq). To quantify this titration, and to make it more pHun, use a wireless pH sensor and a simple setup to keep the focus on the concept.

Recent Chemistry Videos

Here are two from our "PASCO Shorts" series. These videos are all around a minute long and investigate fun or novel uses of our Wireless Sensors in the lab.

First, in Hydrogen Peroxide Decomposition the classic chemistry demo "Elephant's Toothpaste" is made qualitative with the use of our waterproof Wireless Temperature Sensor.

In another classic demonstration heated water vapor displaces air in a can. When put into cold water it quickly recondenses, forming a partial vacuum and atmospheric pressure does the rest. Our Wireless Pressure Sensor allows your students to visualize the pressure change.
