The pH of an enzyme catalysed reaction has to be maintained between 7 and 8. What indicator should be used to monitor and a control the pH ?

Text Solution

AI Generated Solution

To determine the appropriate indicator for monitoring and controlling the pH of an enzyme-catalyzed reaction that needs to be maintained between 7 and 8, we can follow these steps: ### Step 1: Understand the pH range The pH range of interest is between 7 and 8. This range is slightly basic, as a pH of 7 is neutral and a pH of 8 is mildly basic. ### Step 2: Identify suitable indicators Indicators are substances that change color at specific pH levels. To find an appropriate indicator, we need to look for one that changes color within the pH range of 7 to 8. ...

    Acid base indicators are either weak organic acids or weak organic bases. Indicator change colour in dilute solution when the hydronium ion concentration reaches a particular value. For example, phenopthalein is a colour less substance in any aqueous solution with a pH less than 8.3 in between the pH range 8.3 to 10 , transaction of colour (colourless to pink) takes place and if pH of solution is greater than 10 , then solution colour is dark pin. Considering an acid indicator HIn, base In^(-) can be represented as : HIn hArr H^(+) + In^(-) acidic form basic form pH of solution can be computed as : pH = pK_(In) + "log" ([In^(-)])/([HIn]) In general, transition of colour takes place in between the pH range pK_(In) +-1 If an indicator is to be used in an acid base titration having an equivalence point in pH range 8 to 10 , the indicator must
