On your calculator you would input 10, ^, (-), 5 and you would get 0.00001.<br />

This is also the way to find the amount of OH + that are present in a base.<br />

To find the pH: -log(concentration)<br />

To find the concentration: 10 -pH<br />

Define these terms:<br />

pH scale<br />

A ph scale in which measures the acidic of a subtance. It can also measure the level of base it its. Not only thtaht ph<br />

scale can show the mixture of a basea nd aci meaning that its nuetral which the number on the ph is 7.<br />

The scale ranges from 1-14. Acids are from 1 -6 while bases are 8-14.<br />

Hydronium ion<br />

A hydronuim ion is a aqueous solution is no more than a proton. Its a bare nuclues. Contains single postive charge which<br />

is concentrated into a volume of space .The hydronium ion is an vital when their is chemicla reactions<br />

that occur in aqueous solutions.The chemical formula of a hydronuim ion is H3O<br />

Arrhenius acid/base<br />

An Arrhenius acid dissociates in water to form hydrogen ions. On the other hand, an Arrhenius base<br />

dissociates in water to form hydroxide ions. Acid is any substance which delivers hydrogen ion to the solution.<br />

While any substance which delivers hydroxide ion (OH¯) to the solution.<br />

Lewis acid/base<br />

In the Lewis theory of acid-base reactions, the bases give pairs of electrons. While on the other hand the acids take<br />

pairs of electrons. A Lewis acid is a substance, that can take in a pair of nonbonding electrons.<br />

Baicaly a Lewis acid is an electron pair acceptor.<br />

Bronsted-Lowry acid/base<br />

An acid is a substance from which a proton can be removed. A base is a substance that can remove a proton from an<br />

acid.In an acid, the hydrogen ion is bonded to the rest of the molecule. In an acid, the hydrogen ion is bonded to the<br />

rest of the molecule<br />

Strong acid/base<br />

strong acid is any acid that ionizes completely in solutions. Which menas thet it gives the greatest number of hyrogen ion or<br />

protons. While a srong base feel slippery and taste soapy. A strong base is a base that breaks completley apart<br />

in solution.<br />

Weak acid/base<br />

.A weak acid is an acid that dissociates incompfew of its hydrogen atoms into solution. Which makes it is less capable<br />

than a strongacid when giving protons away. While a strong base is a base that does not ionize fully in an<br />

aqueous solution.<br />

Neutralization reaction<br />

Neutralization reaction is when an acid and a base react to form water and a salt and involves the combination of hydrogen<br />

ions and OH- ions to generate water. The neutralization of a strong acid and strong base has a pH equal to 7 which is<br />

nuetral not acidic nor a base but in the middle conating a bit of both.<br />

Titration<br />

Titration is a slow addition of one solution of a known concentration to a known volume of another solution of unknown<br />

concentration until the reaction reaches neutralization, which is often indicated by a color change. Two of the most<br />

common titrations are acid-base and redox titrations<br />
