The High Priest of Globalization in American Culture and Governemnt - One type of titration uses a neutralization reaction, in which an acid and a base react to produce a salt and water: In equation 1, the acid is HCl (hydrochloric acid) and the base is NaOH (sodium hydroxide). When the acid and base react, they form NaCl (sodium chloride), which is also known as table salt. An acid/base neutralization reaction will yield salt and water. In an acid-base titration, the neutralization reaction between the acid and base can be measured with either a color indicator or a pH meter. Acid + Base Salt + Water In this experiment, a phenolphthalein color indicator will be 49memoryblogfc2com.gearhostpreview.com Size: KB. Strong acid - Strong base Table 1: Common Indicators and Their Colours In the above example, pH of the hydrochloric acid will change with increasing amount of sodium hydroxide added. At the end-point the solution will become neutral with pH of 7. This is only true for strong acid-strong base titration. For strong acid-weak base, weak acid. courseworks exe river yoga
