Red cabbage or beetroot juice will do the job.
pH numbers below 7 indicate an acid, with lower numbers indicating stronger acids. pH numbers above 7 indicate a base, with higher numbers indicating stronger bases.
"Slippery" is a subjective descriptor often used to describe substances like soap or oils. The slipperiness of a substance does not indicate whether it is an acid, base, or neutral.
Recreation of an indicator using an acid and a base involves mixing a colorless or faintly colored acid-base indicator with an acid to make the solution acidic (and change color) and then adding a base to neutralize the acid and return the indicator to its original color. This process demonstrates the reversible nature of acid-base indicators and how they can be used to visually indicate the presence of acids or bases in a solution.
An indicator used to detect an acid or base is a substance that changes color in the presence of acids or bases. Examples of indicators include litmus paper, phenolphthalein, and universal indicator solution.
To determine if acid or carbonate was in excess initially, you can titrate the reaction mixture with an appropriate base of known concentration. The point where the base completely neutralizes the acid will indicate the amount of acid present initially. Any excess base after this point would suggest that the initial excess was in the carbonate.

litmus paper indicates wether a substance is an acid or a base if it is an acid the paper is turns red, if base it turns blue

As the name sulfuric acid might indicate, it is a bronsted-lowry acid.
The scale used to indicate the strength of an acid or base is called the pH scale. It ranges from 0 to 14, with 7 being neutral, values below 7 indicating acidity, and values above 7 indicating alkalinity.
Acid + base conjugate base + conjugate acid
An acid typically has hydrogen as the first element in its chemical formula, such as HCl for hydrochloric acid. A base will often contain hydroxide ion (OH-) in its formula, like NaOH for sodium hydroxide. The number of hydrogen ions and hydroxide ions can also indicate the strength of the acid or base.
A solution with a pH of 3 is considered acidic. pH values below 7 indicate acidity, while values above 7 indicate alkalinity. A pH of 7 is considered neutral.
Acetamide is a weak base. It can undergo protonation to form the conjugate acid, acetic acid, in acidic solutions.
