3. Question 2: When we say that plants and animals respire, where exactly is the process occurring? (This potassium hydroxide solution is to absorb the carbon dioxide gas from the air present in the glass bottle so that no carbon dioxide is left in the air inside the glass bottle). A carbon dioxide scrubber is a device which absorbs carbon dioxide (CO2). Answer: CO 2. When a solution of KOH is used in titrations, it must be titrated itself to determine its exact concentration. Similar to glycolysis but runs in reverse. ADVERTISEMENTS: 4. KOH IS USED TO ABSORB CO2, THEREFORE, the net change n gas volume is a measure of OXYGEN consumption. We need pressure to dissolve CO2. Question 18. Write an equation to represent aerobic respiration. fill test tube with germinating peas, cover with cotton, and then add KOH potassium hydroxide. This is because it is constantly absorbing CO2 and loosing its strength as a base. H2CO3 + KOH -> KHCO3 + H2O. Answer: Gases involved during respiration are called respiratory gases. Take a rubber cork which fits tightly into the mouth of the glass bottle and cut it into two halves. KOH is used to absorb the carbon dioxide released during respiration of germinating seeds which creates a vacuum in the flask. We also see that CO2 reacts … Question 3: Why do we use germinating seeds in this experiment? 1 CO2 is added to 1 RuBP and then splits to form RuBP while others are assembled into sugars. They include CO 2 and O 2. Carbon dioxide being an acidic oxide, reacts with alkalis to form the respective carbonates. The result is potassium bicarbonate and water. The CaCO3 is precipitating and not dissolving during this process, because buffering in the ocean maintains a stable pH around 8. Why? When CO2 is bubbled in a concentrated solution of KOH is gets absorbed forming KHCO3 ie the soapy bicarbonate of potassium. Аnswer: Respiration is a chemical process and occurs in mitochondria. What is fermentation? Both of them are alkalis with similar properties. Answer: C 6 H 12 O 6 + 6O 2 ——> 6CO 2 + 6H 2 O + 38 ATP. Answer: The anaerobic … Lots of dissolutions are otherwise categorized as chemical processes that lead to a reaction between 2 species. Name the gas absorbed by KOH solution. ATP is used to make glucose. In order to make 1 molecule of glucose this cycle must be completed 6 times. Question 17. But ordinary solutions hardly absorb any CO2 at 1 atm. “THE oceans take out our anthropogenic carbon dioxide gas by quickly dissolving it as bicarbonate HCO3-, which in turn forms solid calcium carbonate either organically in calcareous organisms or precipitates inorganically. This is one of them. Question 16. Uses products of the light reaction to "fix carbon" meaning carbon dioxide molecules are added to one another. KOH IS USED TO ABSORB CO2, THEREFORE, the net change n gas volume is a measure of OXYGEN consumption. CO 2 is called respiratory gas.
