Apr 17, 2016 · Jones’s Test is an organic reaction for the oxidation of alcohols to carboxylic acids and ketones. This oxidation is very rapid and exothermic with high yields. Tollen’s Reagent was used to determine whether a substance is an aldehyde or ketone, which shows that aldehydes are easily oxidized while ketones are not.

solution. For acid-base titrations the indicators used are weak acids or bases. They have one color in acidic solutions and another color in basic solutions because they undertake different forms in different solutions. An acid-base indicator in acid form undergoes a change when put in water as illustrated by Equation 3. HIn(aq) + H 2 Well, you may have used phenolphthalein as the indicator in a particular titration you performed, but it's not the case that phenolphthalein must be the indicator used for all titrations.

1. Strong Acid with a Strong Base, e.g. HCl with NaOH:Before NaOH is added, the conductance is high due to the presence of highly mobile hydrogen ions. When the base is added, the conductance falls due to the replacement of hydrogen ions by the added cation as H+ions react with OH−ions to form undissociated water.
Put a secret mark on the cup with the sodium hydroxide, or note carefully which student takes the unique cup. You will need a dropper bottle with phenolphthalein pH indicator solution later in the lab. Phenolphthalein is an organic compound (C 20 H 14 O 4) used as an acid-base indicator.

Virtual Labs will be made more effective and realistic by providing additional inputs to the students like accompanying audio and video streaming of an actual lab experiment and equipment. For the ‘touch and feel’ part, the students can possibly visit an actual laboratory for a short duration.
There are two kinds of nucleic acids. I'm Phoebus Levene. By the early 1900s, we knew that Miescher's nuclein was a mix of proteins and nucleic acids. There are two kinds of nucleic acids. DNA — deoxyribonucleic acid — is found mainly in the nucleus. RNA — ribonucleic acid — is found mainly in the cytoplasm.
Acids and bases react with one another to yield two products: water, and an ionic compound known as a salt. This kind of reaction is called a neutralization reaction. Na+ +OH¡+H++Cl¡ ¡! H 2 O+Na ++Cl¡ K++OH++H++NO¡ 3 ¡! H 2 O+K ++NO¡ 3 These reactions are both exothermic; although they involve difierent acids and bases, it has been
Chemistry – S. Martinez Page 2 Acid/Base Titration Virtual Lab 24. What is the pH at the equivalence point? 25. What does the pH at the equivalence point tell you about the strength of the acid and the strength of the base? BONUS QUESTION: Does the equivalence point change based on the strengths of the acids and bases involved in the titration?
There were many possible sources of errors in the lab procedure. Reaction times when attempting to record the time it took for colour to change are extremely variable. Since the procedure included the use of data from other lab groups, this would have a large affect on the results.
