how does hydrochloric acid and sodium hydroxide look apart from colour? {explain more on it}?

Just by looking at any acid or base, its tough to guess. But still you can\n\n(1). Touch the solution with your fingers. If it is sticky like detergent, then its a base.\n(2) Acid smells "Sour" smell.. you remeber Vinegar smell?its acid smell\n\n(3) Open the cap of bottle inside the hood. If it is exibiting fumes then its a "Concentarted acid". If not then it may be a weak acid or a base. To confirm just touch with your fingers and see whether it id sticky or not.\n\n(4) If you have litmus paper then its so simple... if you have a blue litmus paper...which turns into red on treating with some solution then the solution is acid.. (Blue----Red---Acid   You can remeber this easily by first letters in each word..B--R--A)

so do you want the color of Potassium Hydrogen Sulfate (KHSO4), or Sodium Hydrogen Sulfate (NaHSO4)? I guess it wouldnt matter, they would both be colorless anyway. In crystalline form they would be white to clear crystals too.

OH- is an alkali (pH is more than 7) and H+ is an acid (pH is less than 7).\n\nAcid + Alkali -> Neutrality\n\nSince it's neutral, water (pH 7) is produced.\n\nHope my explanation helped c",)

At high pH values (>10), the Hydroxide ion in solution takes protons from the phenolphthalein indicator, forming an ion and water.  The -2 ionic form of phenolphthalein then rearranges the electronic structure to form the characteristic pink color.\n\nSee the wikipedia article for more.

a. by the proccess of titration.  few drops of universal indicator are poured onto the base. acid is poured  slowly with the help of the burette. when the base is decolourised this indicates that it has been neutralised.\n\nb. vinegar\nc. all of the above\nd. 7

The temperature of the sum's surface gives it's characteristic color. If an object with a small hole in it were heated to the same temperature the light comming out of the hole would have the same temperature. i.e., black body radation.\n\nAlso because our eyes the characteristic light as yellow. Namely, the three color sensors in our eyes senses the Yellow more brightly than the red and blue. So, we see yellow.

NaOH ----------------> Na+   +   OH-\nFind the number of moles of NaOH\nMoles of NaOH = 0.10M * 0.150L = 0.015 moles\nSince the coefficients in fornt of NaOH, Na+ and OH- are all 1, therefore if 0.015 moles of NaOH disssociates, 0.015 moles of Na+ and 0.015 moles of OH- are produced.\n\nSimilarly we will work with HCl\nHCl --------------------> H+      +      Cl-\nMoles of HCL = 0.30M * 0.05L = 0.015 moles\nThis means the 0.015 moles of H+ will be produced\n\nSince H+ and OH- have equal amiunts, they will completely neutralize each other leaving the solution at neutral pH. Since the neutral pH is 7, therefore, the pH of this solution will be 7.

In terms of clear crystals and clear solutions, they do not absorb light in the visible range.\n\nIn terms of flame test, they all contain sodium ions, which give off a yellowish light when heated.

Citric acid is a weak acid, while sodium hydroxide is a strong base. The sodium would fall off the hydroxide (because it's strong), so the reaction would be:\n\nHC6H7O7 + OH- --> H2O + C6H7O7

This solution probably has fluorescence at UV (ultra violet) wave length. try looking at it in a room with red light, if there is no light using the lenses then it's confirmed. but you can't simply identify it this way. you have to know the exact wave length that it has fluorescence at. even then you might not be able to identify it. try using UV-visible spectroscopy and when you have its spectra, you can identify it. for more information see: principles of instrumental analysis by Skoog

Sodium hypochlorite is a strong oxidizer. In water, it partially splits into the sodium cation Na+ and the hypochlorite anion ClO−, while a substantial portion hydrolyses into sodium hydroxide and hypochlorous acid. The oxidizing power of the latter and of the hypochlorite anion cause the bleaching effect.\nyea you're right infact soduim hypochlorite is callec bleach.despite the fact that there are other bleaching agents.

The sodium hydroxide should leave a lighter colored trail in the agar as it diffuses into it.  The larger the piece of agar, the thinner the trail will be and the longer it will take to diffuse throughout the entire piece. This has to do with the surface area to volume ratio. A smaller piece would then take a shorter amount of time.

It sort of depends on what you mean by contains water, sodium chloride in water is a solution containing water where water is the solvent.  Hydrochloric acid is another, (that is just HCl dissolved in water).  Hope this helps

Either:\n\n(a) you're not getting a very clean separation, as the peaks should be vivid\n\nor\n\n(b) your detector is insuitable for the acids you're studying.\n\nAtleast, that's my analysis. Any A-Chem experts here?

Very important. The only difference between life giving water (H2-O) and acid used to dye hair blond, Hydrogen-Peroxide (H-O) is the proper ratio of Hydrogen to Oxygen.  There are hundreds of cases like that.

Apart from the precipitation reactions (AgCl and BaCO3 form insoluble compounds, although HCl will dissolve BaCO3), there is flame colouring for identifying the alkali and earth alkali metals (Na yellowish orange, Li reddish, Ba green), there are pH measurements (HCl acidic, NaOH and Na2CO3 basic, rest neutral), and you need to test an oxidant to identify the sugar solution. This ought to give you a matrix which gives only one possible identification for each test (with deionized water failing all tests).
