A milk man adds a very small amount of baking soda (NaHCO3) to fresh milk. Why does this milk take a long time to set as curd Give reason? [2] |
|
Answer» we know that milk turns into curd as time passes due to the formation of lactic acid, and for that to stop we need to add a BASE, so a milk man ADDS a very small amount of baking SODA in order for the milk to remain as milk for a longer time. This is because acid and base reaction is neutral. The milk takes a LONG time to set as curd because the baking soda neutralises with the lactic acid |
