Phenolphthalein lab report

Mix 1 g of methyl orange powder with water. Use 2 drops for each Phenolphthalein lab report mL of solution in a titration. Use as a 0. Put a finger width of the methyl orange powder in the test-tube and add water to half fill the test-tube.

Shake to make the powder dissolve. Add tartaric acid powder until the colour changes to red. Sodium carbonate change this red liquid to orange.

Add a finger width of sodium carbonate to the red liquid until the colour changes back to orange again. Shake the test-tube to help the mixing.

It is a sensitive indicator for titration of weak organic bases and ammonia.

Leave the first test-tube as a control. Add drops of HCl to the second test-tube until the pink colour disappears. Add 3 pellets of solid sodium hydroxide to the third test-tube.

Add colourless phenolphthalein indicator to lime water. The liquid turns pink. Blow into the liquid through a drinking straw. The pink colour disappears and the liquid becomes cloudy. Boil red rose petals in some water until the petals have almost lost their colour and a pink solution forms.

Test this pink solution with acids and bases. Wave a bluebell flower closely over an ant nest.

The angry ants rush out to squirt formic acid on the bluebell flower and the blue pigment in the petals turns red. Also, mix a spoonful of fruit jam with warm water then filter it to get a colourless liquid. Test the solution with acids and bases. Soak cut pieces of red cabbage leaf in boiling water for 30 minutes then remove them.Calcium Carbonate Content of Limestone Experiment ## 5 c.

Since it takes at least 6 hours to work, it is often taken at bedtime to produce a laxative effect the following morning. 85% of what is ingested is excreted in the feces; the remainder is absorbed and eliminated mostly in the urine.

See Laboratory Report. Clinical. In this experiment, a phenolphthalein color indicator will be used. Phenolphthalein is colorless in acidic Four lab periods assigned for this experiment. In part I you will prepare an acid (HCl) solution and a base Chemistry Experiment 7 Page 5 7.

Repeat the procedure for a total of 2 trials. Phenolphthalein indicator was used to show when the reaction was fully neutralized. In an acidic solution, phenolphthalein was colorless and in a basic solution, pink. When the acidic solution, HCl, was neutralized with the basic solution, NaOH, the reaction reached the equivalence point.4/4(5).
