Why methyl orange alkalinity equal to total alkalinity?
Alkalinity is different from basicity, which is directly related to the pH. The higher the pH, the more basic the water.Like acidity, there are different ways to measure and report alkalinity;The first is to titrate the water with acid titrant to the phenolphthalein end point. This is called the phenolphthalein alkalinity. Since phenolphthalein changes color at pH~8.3, this corresponds to a pH where all the CO32- present would be protonated.Second, acid titration to a methyl orange end point, pH~4.3, further converts the bicarbonate to aqueous carbon dioxide. At this end point, some of the weaker conjugate bases are protonated. The methyl orange end point titration indicates total alkalinity.
How methyl alcohol and ethyl alcohol?
First we have to know the difference between methyl and ethyl and alcohol groups: A methyl group chemical formula is CH3- , of an ethyl group it is C2H5- , and alcohol group means the group contains -OH So methyl alcohol is methanol, CH3OH, and ethyl alcohol is ethanol, CH3CH2OH.
Why is there a need to use two indicators in titrating a carbonate mixture?
One single probe may contain two bases: Either OH- and CO32-, or CO32- and HCO3- . (All three of them is non-coexsistant, hence it is impossible)Titration with strong acid will reach the first equivalence point at pH = 8 (phenolphtaleine change to colorless) when both, or one, of these completed reactions: OH- + H+ --> H2O (if OH- is present) andCO32- + H+ --> HCO3-Further titration with strong acid, after addition of methyl orange indicator will reach the second equivalence point at pH = 4 (methyl orange changes from orange-yellow to red) when this reaction is completed : HCO3- + H+ --> H2CO3From the difference and total of these two titrtions (done with the same probe in two steps) both compounds can be determined.
How do you make orange peel lip gloss?
First, peel an orange, then... rub it all over your lips!! ;)
What is the difference between ethyl and methyl alcohol?
Methanol, also known as methyl alcohol, is madeof molecules containing one methyl group, with a chemical structure of CH3-OH. Methanol is highly toxic if inhaled, drunk, or absorbed through the skin and can cause blindness. Ethyl alcohol is the same as ethanol or grain alcohol. I has two methyl groups and looks like CH3-CH3-OH. This is the type of alcohol found in the alcoholic beverages people consume. Both compounds are organic and are good solvents and fixatives.
How does column chromatography separate a mixture of methylene blue and methyl orange?
Methylene blue and methyl orange will have different binding affinities with the column material, and thus one will pass through the column more slowly than the other. This will result in one of the compounds being eluted from he column before the other. The one with the weakest binding to the column will be eluted first.
Can you use methyl orange and phenolphthalein fro weak acid weak base titrations?
first of all remember that titr'n b/w weak acid and weak base is impossible. weak acid*strong base-phenolphthalein str acid*weak base-methyl orange if both are strong can use both.
What is the chemical formula for methyl orange?
Methyl orange is synthesized by reaction of sulfanilic acid, sodium nitrite, and dimethylaniline. First, sulfanilic acid is dissolved in dilute aqueous acid. Sodium nitrite is added to produce a disowning salt .Chemical formula of Methyl Orange: C14H14N3NaO3S

Why methyl group cannot be present at first carbon of the chain?
If a methyl group is on the first carbon, then you're just adding another carbon onto the longest chain. So if I have propane (3 single-bonded carbons) and I add a methyl group onto the end, I have 4 single bonded carbons in a row - which means I now have butane.
Who was the first orange president?
Donald trump was the first orange president
If there are buds on my orange tree and I think they're oranges but some of my family thinks they're flower buds can anyone tell me which they are?
Orange trees have to flower first before a fruit can form. If your tree has not flowered, they will not be oranges, as the orange forms from the middle of the flower. If what you think is a bud is growing from the center of a recent flower, then it is a small orange. Oranges first appear there as a small green, hard ball that looks like a tiny orange.
