Ocean acidification
What is ocean acidification?
Ocean acidification refers to the process where the ocean's pH decreases due to the absorption of excessive CO2 from the atmosphere
What is acids?
Acids are substances that donate protons (H+ ions) in a chemical reaction.
What is climate change?
Climate change refers to any long-term shifts in climate patterns, including changes in temperature, precipitation, and other weather variables.
What is the definition of a conjugate acid-base pair?
A conjugate acid-base pair are two species that are related by the gain or loss of a single proton (H+).
The number of moles of solute per liter of solution
Why is it happening?
Human activities, particularly the burning of fossil fuels, deforestation, and industrial processes, release massive amounts of CO2 into the atmosphere.
What are bases?
Bases are substances that accept protons (H+ ions) in a chemical reaction.
What is the difference between climate change and global warming?
global warming specifically refers to the increase in the average temperature of the Earth's surface, while climate change encompasses a broader range of changes in climate patterns.
How does an acid relate to its conjugate base?
An acid is a proton donor, and its conjugate base is formed when it loses that proton.
What are Moles?
The number of particles (atoms or molecules) in a substance, related to its mass and molar mass.
What are the impacts on marine life?
Ocean acidification affects various marine organisms, including those that use calcium carbonate to build shells and skeletons
What is pH?
The pH scale measures the acidity or basicity of a solution.
What are the main causes of climate change?
Human activities that release greenhouse gases, such as burning fossil fuels for energy, deforestation, and industrial processes, are the primary drivers of climate change.
How does a base relate to its conjugate acid?
A base is a proton acceptor, and its conjugate acid is formed when it gains a proton.
What is a Solute?
The substance being dissolved in the solution.
What can be done to address ocean acidification?
The most effective way to address ocean acidification is to reduce CO2 emissions from human activities.
What do acids donate?
Acids donate protons (H+) and bases accept protons.
What are the potential impacts of climate change?
Climate change can lead to rising sea levels, more frequent and intense extreme weather events (like heat waves, droughts, and floods), disruptions to ecosystems, and impacts on human health and agriculture.
How does a base relate to its conjugate acid?
A base is a proton acceptor, and its conjugate acid is formed when it gains a proton.
What is the molarity of a solution that contains 2.5 moles of NaCl dissolved in 500 mL of solution?
First, convert mL to L: 500 mL * (1 L / 1000 mL) = 0.5 L Then, calculate molarity: Molarity = moles of NaCl / volume of solution (L) = 2.5 moles / 0.5 L = 5.0 M
How does ocean acidification affect fisheries?
Ocean acidification can impair the growth and survival of shellfish, which are important for fisheries.
What are the 5 examples of acids and bases?
Acids: Hydrochloric acid, sulphuric acid, nitric acid, lactic acid, hydrobromic acid. Bases: Potassium hydroxide, sodium hydroxide, calcium hydroxide, lithium hydroxide, cesium hydroxide.
What can I do to help address climate change?
Reducing your carbon footprint through actions like using less energy, eating less meat, and advocating for policy changes can help address climate change.
Give an example of a conjugate acid-base pair
H2O and H3O+ (hydronium ion) are a conjugate acid-base pair.
What is the molarity of a solution that was prepared by dissolving 14.2 g of NaNO3 (molar mass = 85.0 g/mol) in enough water to make 350 mL of solution?
0.477 M
