Well, hyperventilation is the state of breathing faster or deeper (hyper) than necessary, and thereby reducing the carbon dioxide concentration of the blood below normal. This causes various symptoms such as numbness or tingling in the hands, feet and lips, lightheadedness, dizziness, headache, chest pain, slurred speech and sometimes fainting.
The reason it causes the blood pH to increase is because of the levels of carbon dioxide...carbon dioxide gets converted into bicarbonate and hydrogen ions. So basically a decrease in carbon dioxide levels in the blood will increase the pH of blood. The reason is because carbon dioxide breaks up into bicarbonate (H2CO3), which is a buffer used to maintain blood's pH. But if there are not enough carbon dioxide molecules then there will be no dissociation and therefore an increase in pH. Since pH is a measure of the activity of hydrogen ions (H+) in a solution and, therefore, its acidity or alkalinity. pH= pK+Log [HCO3-]/[H2CO3] determines the pH of blood.

Bicarbonate Ions are HCO3-, where as carbonate ions are H2CO3. The equation is as follows:
HCO3- + H+ <=> H2CO3 <=> H2O +CO2
When the blood is basic (there are too many H+ ions floating around in the blood) then HCO3- will bind to H+ to form H2CO3 making the blood pH drop. When there aren't enough H+ ions in the blood H2CO3 will loose one H+ increasing the pH of the blood.

Presence of higher CO2 levels cause an increase in blood pH levels ... since the CO2 is not being moved out as quickly, the resultant acid content will increase (CO2 concentrations can lead to carbonic acid development).

you breathe out CO2. CO2 dissolved in the blood binds to water to form carbonic acid. When you breathe out a lot of the carbon dioxide, more carbonic acid dissociates, reducing acidity and raising pH. This is called respiratory alkalosis.

the body uses a pH increase to release CO2. when you hypervenatle you are breathing out more CO2 than normal
