Introduction when you think of ph, you probably think of acidic and basic solutions but soil can be acidic or basic, too soil ph, sometimes referred to as soil acidity, can be expressed using the ph scale the ph scale ranges from 0 to 14. If we add ph 4 or ph 10 buffers to a 5% amylase and a 2 percent starch solution, the buffers will denature the amylase and make it ineffective the ph 7 and 8 buffers will not denature it because of how neutral they are, so they will not make the amylase ineffective the expected results were the ph.
