pH Balance

PH scale

• measures the concentration of hydrogen ions in a solution

• measures the concentration of hydroxide ions in a solution

• measures the concentration of salt ions in a solution

Each pH unit requires ............. fold in the amount of hydrogen ions.

• ax10

• a/10

• ax2

buffer means

• Adding or removing OH ions to overcome any change in the ocean's PH

• Adding or removing carbon atoms to overcome any change in the ocean's PH

• Adding or removing H ions to overcome any change in the ocean's PH

In areas with a lot of photosynthesis the pH will be

• lower,because plants produce H ions

• higher, because CO2 is used by the plants

• neutral

In warm areas the solubility is also low, so the amount of CO2 in the water will be low, so the pH will also ..........

• decrease

• remain the same

• increase

n water solutions CO2 is present in many forms

• carbonic acid

• bicarbonate

• carbon dioxide

• A and B

a scale used to specify how acidic or basic a water- based solution is. Acidic solutions have a lower pH, while basic solutions have a higher pH

• pH Scale

• triple beam balance

• grocery store scale

• plate scale

Define an acid

• any compound that increases the number of hydrogen ions when dissolved in water

• fruit juice, milk, and water

• anything that fits in a beaker and is used in science class where the teacher wants you to use your bare hands. You never have worry about your safety

• A kind of music traditionally listened to by people around a campfire

Define a Base

• any compound that increases the number of hydroxide ions when dissolved in water

• Helium when mixed with Sodium and evaporated into a paper bag

• The higher notes on a music score

• any element that decreases the volume of nitrogen ionic bonds when absorbed by acid
