Acids and Bases *Unit 1

Question 1

What type of medium are acids and bases

Answer 1

electrolytes

Question 2

Acids

Answer 2

• proton donors
• they release hydrogen ions
• less than ph of 7 is acidic

Question 3

Bases

Answer 3

• Proton acceptors
• they pick up H+ ions
• more than 7 is basic

Question 4

Normal Blood Ph

Answer 4

7.4

Question 5

Alakalosis PH

Answer 5

If blood PH is more than 7.45

Question 6

Acidic PH

Answer 6

If blood PH is less than 7.4

Question 7

What can be the causes for a problematic PH?

Answer 7

Metabolic or Respiratory

Question 8

Metabolic Indicator

Answer 8

Bicarbonate - buffer in blood

Metabolic Acidosis HCO3- is less than 24
Metabolic Alkalosis HCO3 is when the level was more than 24

Question 9

Respiratory Indicator

Answer 9

Partial pressure of carbon dioxide (PCO2) is the measure of carbon dioxide within arterial or venous blood. CO2 is acidic.

Respiratory Acidosis PCO2 occurs when the level is more than 40mmHg
Respiratory Alkalosis PC02 occurs when the level is less than 40 mmHg
