A pH meter gives a direct reading which is great when testing wine or soft drinks.

Litmus paper will go red in acid or blue in base.

An acid will liberate carbon dioxide from chalk - a base will not

You cook a red cabbage and save the juice. then if the thing you are testing turns red in the juice, it is acidic, if blue basic.

Turmeric indicates acid by turning strong yellow. Base is indicated by red.

Phenolphthalein indicates bases by turning red or purple. Acid is indicated by no color.

How can one determine a Bronsted-Lowry acid and base?

A Bronsted-Lowry acid is a substance that donates a proton (H) in a chemical reaction, while a Bronsted-Lowry base is a substance that accepts a proton. To determine if a substance is a Bronsted-Lowry acid or base, you can look at its behavior in a reaction - if it donates a proton, it is an acid, and if it accepts a proton, it is a base.

Can universal indicator be used to determine the strength of acids and bases?

Yes, universal indicator can be used to determine the strength of acids and bases. It changes color over a range of pH values, allowing you to estimate whether a substance is an acid or a base and roughly how strong it is based on the color change. However, it is not as precise as using pH paper or a pH meter for accurate pH measurements.
