    as acid base indicators. We found that the equivalence point of the titration of hydrochloric acid with sodium hydroxide was not within the ph range of phenolphthalein’s color range. The titration of acetic acid with sodium hydroxide resulted in an equivalence point out of the range of methyl red. And the titration of ammonia with hydrochloric acid had an equivalence point that was also out of the range of phenolphthalein.. The methyl red indicator and the phenolphthalein indicator were unsuitable

    prediction; information you have researched before Diffusion refers to the passive movement of molecules along the concentration gradient. In this case we will be looking at the diffusion of acid in agar blocks. Agar is a jelly like substance and the indicator methyl orange is added which will turn red in the presence of acid. Hence we can measure the time taken for the colour change to calculate the rate of diffusion of hydrochloric acid in agar blocks. Variables Independent variable Concentration

    to the addition of corresponding pH indicators and the variation of colors depending on its pH level was used as standards. At the end of the experiment‚ the colors of the unknowns were compared with the standard buffer solutions and then calculated  to obtain an estimation of their pH or acidity. Experimental results show that Solution A‚ B‚ C‚ and D‚ have pH levels of 4.9‚ 5.2‚ 4.2‚and 4.9 respectively. Keywords: McIlvaine buffers‚ colorimetry‚ pH indicators‚ Henderson-Hasselbalch equation
