from the research i have done so far, you can use camote tops as a pH indicator
gather the reddish leaves, boil in some water then pour it through a sieve. The liquid you get acts similarly to what you get with cabbages. They turn pinkish-reddish when exposed to acids and bluish-greenish when exposed to bases
To determine the purity of an amino acid using paper chromatography, you would first need to separate the amino acids using paper chromatography. Once the amino acids are separated on the paper, you can calculate the Rf value (retention factor) for each amino acid. Comparing the Rf values of the sample amino acid to a standard of known purity can help determine the purity of the sample.
An acid is a substance that produces H+ ions in a water solution. Examples include hydrochloric acid (HCl) and sulfuric acid (H2SO4).
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.
Nitration of benzoid radicals present in the amino acid side chain occurs due to reaction with nitric acid giving the solutions a yellow colouration. This test is answered by aromatic amino acids like tyrosine and tryptophan. Phenyl alanine gives a weak positive reaction. When a preotein solution is heated with concentrated nitric acid, the benzene ring under goes nitration to form yellow nitro derivatives. When treated with NaOH the sodium salt formed is tense orange in color.
a substance which is classified as neutral has a ph of 7- using universal indicator this will result in green. an acid is anything from ph1 to ph6 depending on the concentration of the acid, to neutralise an acid from a ph of 6 or below an alkali is required, so when an acid turns neutral it has either reacted with an alkaline substance or has a higher ph
One can determine the acid dissociation constant (Ka) of a substance without using the pH value by conducting a titration experiment. In this experiment, a known concentration of the acid is titrated with a strong base of known concentration. By measuring the volume of base required to neutralize the acid, one can calculate the Ka value using the initial concentrations of the acid and base.
Because acid can poison you! You could die!!!!!!!!! There are harmful chemicals in acid! If you want to determine if a substance is an acid, try pouring it into a container and see if it bubbles.
One can effectively test for methanol in a substance by using a simple chemical test called the chromic acid test. This test involves mixing the substance with chromic acid and sulfuric acid, and observing a color change to determine the presence of methanol.
A strong acid is a substance that completely dissociates in water to produce a high concentration of hydrogen ions. You can determine if a substance is a strong acid by testing its ability to fully ionize in water and produce a low pH level below 7.
Phenolphthalein is colorless in acidic solutions and pink in basic solutions. By adding phenolphthalein to a substance, you can observe the color change to determine if the substance is acidic or basic based on the change in color.

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.
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.
To determine if a substance is a weak acid, you can test its pH level. Weak acids have a pH level slightly below 7, indicating they release fewer hydrogen ions compared to strong acids.
A strong acid is a substance that completely dissociates in water to produce a high concentration of hydrogen ions. One way to determine if a substance is a strong acid is to test its ability to conduct electricity in water, as strong acids are good conductors of electricity due to the high concentration of ions they produce.
Yellow is not a definitive indicator of whether a substance is an acid or an alkali. The color of a substance is not directly related to its pH or acidity levels. pH testing is required to determine if a substance is acidic or alkaline.
