Carrying Out a pH Titration (Leaving Cert Chemistry): Flashcards

Experimental technique monitoring $\text{pH}$ changes as acid/base is gradually added

Provides precise numerical data throughout entire process

Measures $\text{pH}$ precisely and sends data to computer

Ensures thorough mixing of solutions

Around $\text{pH} = 7$

Below $\text{pH} = 7$ (acidic side)

Phenolphthalein

$\text{pH}$ change is too gradual throughout

$\text{pH}\,8-10$

$\text{pH}\,3-4$

Methyl orange

Exact readings, work for all titration types

Look for steepest part of curve
