Acids and Bases

Litmus paper suits a quick acid-or-base check, pH strips give a readable 0-14 value, and a digital pH tester gives an exact numeric reading. Choose based on what your practical actually needs.

Different indicators change colour at different pH ranges. A universal indicator suits general classroom testing, while titration practicals may need a specific indicator matched to the acid-base pair being tested.

A digital pH tester is reusable across many practicals, while litmus and pH strips are consumed with each test. Budget for enough consumable strips to cover a full term of practicals.

A single demonstration set suits teacher-led lessons, but hands-on acid-base practicals need enough test strips, testers and titration apparatus for every group to run the experiment themselves.

Litmus paper only shows whether a solution is acidic or alkaline through a simple colour change. pH test paper gives a more precise reading across the full 0-14 pH scale when compared against a colour chart.

Our digital pH tester gives a numeric reading to 0.1 pH resolution, more precise and repeatable than a colour-chart comparison. Test strips remain a fast, low-cost option for general classroom use.

A standard titration setup needs a burette, retort stand and clamp, a conical flask, an appropriate indicator solution, and the acid and base solutions being tested. Our titration apparatus and pH indicator dispenser support this practical directly.

No. pH test paper and litmus paper are single-use consumables, changing colour permanently on contact with a solution. Budget for enough strips to cover a full term of practicals.

Yes. We regularly supply schools with class sets of litmus paper, pH test strips and titration apparatus. Contact us for a quote on bulk quantities for a full classroom or department.
