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.

What is acid base indicator?
An acid base indicator is a chemical substance that has the ability to change color depending on the pH.
Can you know from its name if an acid or base is strong or weak?
It's not possible to determine whether an acid or base is either strong or weak. The only way is to see it's concentration. To determine whether the liquid is an acid or base is easy. An acid's chemical formula always has Hydrogen ions. Example HNO3 or HCl. Bases always have OH or Hydroxide. Example NaOH2.
Substance that is of one color in an acid solution and of another color in a basic solution is a what?
A substance that changes color depending on the pH of the solution is known as an acid-base indicator. These indicators are often used in chemistry to visually determine the acidity or basicity of a solution based on the color change they exhibit.
What is the definitions of an acid base and salt as they apply to chemistry?
An acid can be viewed as a substance that provides protons (H+) to solution. A base can be viewed as a substance that accepts protons or that provides hydroxyl ion (OH-). A salt is a substance that results from the reaction of an acid and a base.
Is caustic acid or base?
It doesn't matter if the substance is basic or acidic. What makes a substance destructive is the strength of the substance.
What makes a base or an acid?
To determine whether a substance is an acid or a base, you look at it's pH. If it is over 7, it is a base. If it is below 7, it is an acid. If the pH is 7, the substance is neutral.
What things could be used to determine whether a substance is an acid or a base?
litmus paper.
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.
What determine the properties of a solution?
Whether or not it's an acid or a base
How can you determine if substance is acid or base?
pH paper and litmus paper
How might a scientist do an experiment to tell whether a substance is a base or acid?
kaka
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.
A substance that is used to determine an acid or base is called?
An indicator is a substance that is used to determine whether a solution is acidic or basic by changing color based on the pH of the solution. Examples of indicators include litmus paper, phenolphthalein, and bromothymol blue.
What is used to identify an acid or a base?
A pH indicator is commonly used to identify whether a substance is an acid or a base. Acids turn pH indicators red, orange, or yellow, while bases turn them green, blue, or purple. pH paper strips can also be used to determine the acidity or basicity of a substance based on the color change.
What is the use of a litmus paper?
litmus paper is genrally used to verify whether a substance is acid or base
Can an amphoteric compound act like an acid and a base?
Am amphoteric substance can react as a base but also as an acid.
What test can you know if it is a acid or base?
You can test whether a substance is an acid or a base using litmus paper. When dipped in the substance, blue litmus paper turns red in the presence of an acid, while red litmus paper turns blue in the presence of a base.
