Virtual lab: practice an acid-base titration in a 360° laboratory

A virtual chemistrand theb that runs in the browser: the student locates the safety equipment, puts on PPE, identifies titrant and analyte, measures the aliquot, prepares the burette, titrates drop by drop, reads the endpoint and calculates the concentration. As many attempts as needed, no reagents, no broken glass and a record of every decision. This is how universities and high schools prepare the in-person practice.

Try it: run an acid-base titration from start to finish

One 360° lab scene, nine procedure steps, three decisions (reagents, endpoint and calculation) and the burette mechanic.

  • Shower, eyewash, rules and fume hood before starting
  • PPE, volumetric pipette, indicator and filled burette
  • Drop-by-drop titration with the burette stopcock (press and hold)
  • Endpoint reading and concentration calculation

What is a virtual lab?

A virtual lab is an interactive simulation of a laboratory practice in which the student follows the real procedure (safety, glassware, measurements, observation and calculation) without reagents, physical equipment or risk. In our 360° version the lab is a photographed space with its fume hood, shower, eyewash and bench; every procedure step is a point of interest and the key decisions (what goes in the burette, when to stop the titration, how to calculate) are assessed with feedback. It does not replace the in-person practice, where manual skill is learned: it prepares it, so the student arrives at the real lab knowing what to do, in what order and why.

What the student practices in this virtual lab

The full titration procedure, with the decisions that cause the most mistakes in real practice.

  • Safety first

    Locate shower, eyewash and fume hood, read the rules and put on PPE before touching a reagent.

  • Titrant and analyte

    Identify which solution goes in the burette and which in the flask from the bottle labels.

  • Measuring the aliquot

    Volumetric pipette with bulb, 25.0 mL into the Erlenmeyer flask, without blowing out the last drop.

  • Preparing the burette

    Rinse, fill, purge bubbles and read zero with the meniscus at eye level.

  • Titration and endpoint

    Drop by drop near the end, constant swirling and recognizing the persistent pale pink of phenolphthalein.

  • Recording and calculating

    Write down the volume used and calculate the concentration with C₁V₁ = C₂V₂, with significant figures.

01

Why use virtual labs in universities and high schools?

Because real lab time is scarce and expensive: reagents, glassware, small groups and one instructor per session. When the student arrives without knowing the procedure, the session goes to explaining instead of practicing. With a virtual lab, the student runs the practice as many times as needed before the in-person session, makes the typical mistakes (overshooting the endpoint, inverting the volumes in the calculation) and gets the explanation on the spot. The instructor sees, per student, which steps they mastered and where they failed, and devotes the real session to manual skill and discussion of results. For institutions with many groups or campuses, it is the way to give everyone the same quality of practice.

02

Which practices can be simulated?

Any procedure with steps, decisions and results: titrations, solution preparation, chromatography, theectrical circuits, instrument measurements, microscopy, dissections, clinical sample analysis or engineering practices. The burette mechanic in this demo (press and hold to dose) adapts to any continuously controlled instrument. Each practice is designed with the course instructor from their lab guide and assessment criteria.

03

How do we adapt the virtual lab to your institution?

We photograph your real labs in 360° (so the student recognizes the space) or use generic scenes, load your practice guides and rubrics, and deliver each practice as a SCORM or xAPI package for Moodle or your institutional platform, with automatic grading of decisions and attempt tracking. We can integrate it with your learning paths and close each practice with a verifiable micro-credential.

What the virtual lab records for each student

Data for the instructor and for the institutional platform.

1

Procedure sequence

Whether they followed the guide order or tried to titrate without preparing the burette or without PPE.

2

Conceptual decisions

Titrant and analyte, endpoint reading and calculation setup, with every option chosen.

3

Typical mistakes

Overshooting the endpoint, inverting volumes, adding more indicator: each explained and counted.

4

Attempts

How many times they repeated the practice until completing it without errors.

5

Time

How long each step and the whole practice took.

6

xAPI log

Every action as an "actor-verb-object" statement for your platform's LRS.

In-person practice alone vs. practice with a prior virtual lab

The real lab is still the goal; the virtual one makes real time count more.

Process

How we build your custom simulator

Five phases with a deliverable you approve in each one.

  1. On-site survey

    360° photos and video of the area, the current procedure and an interview with the expert.

    Deliverable: technical script

  2. Instructional design

    Target behavior, critical decisions, frequent mistakes and the feedback for each one.

    Deliverable: storyboard and decision tree

  3. 360° scenario or 3D model

    Panoramas with hotspots, or the machine modeled when its movement must be simulated.

    Deliverable: navigable scenario

  4. Logic, rules and measurement

    Steps, interlocks, checklist, score and the xAPI events that will reach your LMS.

    Deliverable: working simulator

  5. Packaging and pilot

    SCORM or xAPI tested on your platform and a pilot with real staff before launch.

    Deliverable: published package and report

Other training simulators

Every scenario runs in the browser and is delivered as SCORM or xAPI.
