Acids and Bases, Measuring Speed and Acceleration

Flashcards about Acids and Bases and Measuring Speed and Acceleration

Neutralisation

When an acid and a base react together and cancel or neutralize each other to produce salt and water.

Neutralisation reaction formula

acid + a base → a salt + water

Acid-base titration

A process where an acid is placed in a burette and added slowly to a base with an indicator in a conical flask until the indicator changes color at neutralization.

Purpose of Titrations

To find out exactly how much acid is needed to neutralise a base.

Neutralization with Carbonates

Acids can be neutralized by reacting them with carbonates, producing salt, water, and carbon dioxide gas.

The effect of acids in water

When laboratory acids are dissolved in water, the hydrogen atoms separate from the other atoms; it is these free hydrogen particles (ions) that make a solution acidic.

The effect of bases in water

The common laboratory base sodium hydroxide (NaOH) will dissociate when added to water.

Speed Definition

distance / time

What happens during neutralisation?

When you add an acid to a base they neutralise, all the ions are rearranged and the products salt and water are formed.(H++ OH-¹ → H₂O)

Motion

Motion, or movement, is happening around us every day.
