PPT-Acid/Base Chemistry The pH scale and what does it mean?

1 pH What is it What does it mean How do you measure it Can you determine other things from pH 2 pH an Overview pH is the measure of the concentration of hydrogen ions is a solution pH is measured on a log scale. Titration. Acid–Base Titration. The concentration of a weak acid or a weak base in water is difficult – if not impossible – to measure directly.. But we can calculate the concentration from the results of titration.. Acids and Bases. Properties and Examples.

How do we know that a chemical is an acid?. Most Acids start with an ‘H’ in their chemical formula. What are the properties of an Acid?. Tastes sour. Turns blue litmus paper red. Just a few reminders. What makes an acid an acid?. A . Bronsted. -Lowry Acid is a compound that donates a proton (a hydrogen ion with a positive charge, H. +. ). Think of the standard acids that are commonly mentioned in Gen . Velázquez. Research . Biology. What is pH. ?. pH. stands for the potential of Hydrogen. Is the concentration of hydrogen in a given substance.. [ ]. is the symbol for concentration.. In other words pH is . Acid. is defined as a substance which when dissolved in water gives hydrogen ions. (H +) . Examples.. Base is defined as a substance which when dissolved in water gives hydroxyl ions. (OH-) .
