Lab 15 Electrolytes, Water, Acids & Bases BIO202L
Student Name: Taminderpal kaur
Access Code (located on the lid of your lab kit): AC-54NRLKM
Pre-Lab Questions:
”1. How can eating a high-salt diet increase blood pressure?”
It can raise the amount of Na+ in the blood. Kidneys do filter out the excessive sodium with ex-
tra sodium our body hold on to this water and it increases our blood volume and our vessels
have to Work so hard to get rid of excess sodium which raise high blood pressure.
”2. Research the following disorders and write a definition for each: ”
”a. Acidemia: ” serum PH<7.35.
”b. Alkalemia: ” serum PH>7.45.
”c. Acidosis: ” build from high acid in blood.
”d. Alkalosis: ” high alkaline in blood caused by high levels of bicarbonate.
”3. Name three ways the body regulates the pH of blood. ”
Kidneys maintain the acid base balance by getting rid of acids and bases in blood. Lungs also
help maintaining the balance by getting rid of CO2.
Experiment 1: Breathing and Acid-Base Balance
Table 1: Color Change of Sodium Bicarbonate Solution With and Without the Addi-
tion of CO2
Beaker Starting Color Final Color Time to Change to Final Color
1 Light pink Color got slightly lighter. 5 minute
Color changed to clear as
2 Medium pink. 4 mintue.
water.
Post-Lab Questions
”1. Was the time required to change the solution different for the two beakers? Why or why
not? ”
yes, because I used the extra time for first beaker to blow out bubbles with straw to see if color
will change. Second beaker the color changed a lot faster with difference of 1 minute.
Experiment 2: Urine pH
Test Results:
”Leukocytes: ” 15
”Nitrate: ” negative
