    In a labratory. A solution of Ammonium chloride was given, for us to find the concentration by techniques of back titration. NaOH was added to the diluted ammonium chloride and heated. Then Titrated with HCL adding few drops of bromocresol green indicator. Colour turned yellow.
    What does this mean? I have done the calculation. here are the results:
    Volume of hcl used=23.50ml
    Moles of NaOH=.001773
    Moles of NH4CL=0.02216
    Gram of NH4CL=237g/L

    What does this all means.

    In pure water, there are always small amounts of hydrogen ions and hydroxyl anions present. These arise from the partial ionization of water:

    An acid is any substance which, when dissolved in water, tends to increase the amount of H . In this example, it is hydrochloric acid:

    A base is defined to be any substance which, when dissolved in water, tends to increase the amount of hydroxide. In this ...
