Acids, Bases and Titrations: Free Course

About this course

Practise the reasoning behind acid-base calculations in this free Ninja Nerd course. The complete nine-video chemistry sequence covers acids and bases, strong and weak calculations, salts, approximation checks, percent ionization and three titration combinations. The title reflects the source’s focused acid-base scope rather than promising a whole general-chemistry syllabus.

Course Overview

The course begins with acids and bases and then introduces strong-acid and strong-base calculations. The salts lecture and weak-acid and weak-base calculations broaden the reasoning. The five-percent-rule and quadratic-equation recording addresses the choice of a calculation approach, followed by percent ionization. The final three videos compare the titration cases covered in the source: strong acid and base, weak acid with strong base, and strong acid with weak base. All nine recordings remain available. This is a focused classroom calculation course rather than a complete general-chemistry program or laboratory-safety qualification. Its useful outcome is the ability to explain the assumptions behind an example and check whether the method matches the situation being studied.

How to study the course

• Study the introduction and strong calculations first. Write down the quantities and assumptions before copying a numerical procedure.
• Continue through salts, weak calculations, approximation checks and percent ionization. Compare why a method is selected rather than treating every example as the same problem.
• Complete all three titration lessons and build a comparison sheet. Revisit the prerequisite calculation lesson when the reasoning in a titration stage is unclear.

Use the searchable classroom lesson list to revisit a specific explanation. Pause after a useful demonstration, reproduce a small example and explain the result in your own words. Keep a short note of what worked, what changed and what you still need to understand before moving on.

Who is this for?

This course suits students studying introductory chemistry, health-science prerequisites or acid-base calculations within a formal course. It is particularly helpful when familiar formulas are difficult to connect with the assumptions in a problem.

Before you start

Basic algebra, logarithms and introductory chemical terminology are recommended. A calculator and notebook are useful for practice. The videos are for educational calculation study; they do not provide laboratory supervision, experimental safety training or assessed academic credit.

Put the lessons into practice

Choose a small calculation example from the strong and weak sections and reproduce it on paper, listing the known quantities and the assumptions used. Check the approximation or alternative calculation discussed in the course rather than selecting a method automatically. Then compare one example from each titration recording, explaining why the reasoning changes between cases. Keep this an on-paper exercise without handling chemicals. Finish with a short checklist that helps you identify the type of problem, select a relevant source lesson and verify the meaning of your result.

This optional activity is provided by WikiFree for independent practice. It is not a graded assignment from the instructor. Keep your working notes, check the result against the task you defined and return to the relevant lesson when an assumption or technique is unclear.

Certificate / Assessment

Watching the public videos and using WikiFree progress tracking does not award a certificate, exam voucher, academic credit or instructor assessment.

Use your practice output to review what you can now explain and repeat independently. Completion tracking records your study progress; it does not replace an assessed qualification or professional experience.
