Koby needed to break the baking soda to provide a larger surface area for reaction thereby increasing the rate of reaction.
<h3>Rate of reaction?</h3>
The term rate of reaction refers to how quickly or slowly a reaction proceeds. The surface area of solid reactants is an important factor that influences the rate of reactions when a solid reactant is involved.
Hence, Koby needed to break the baking soda to provide a larger surface area for reaction thereby increasing the rate of reaction.

The molarity of H2SO4 is the number of moles in 1 L of solution.
The molarity is 2.0 mol/L
This means that there should be 2 moles in a 1 L solution to make up this molarity.
In this case we need to make up a 5 L solutions with that molarity. Then the amount of moles required are - 2 mol/L x 5 L = 10 mol
Answer:
storage solution , deionized water, stabilizes
Explanation:
A pH meter is a scientific device or instrument that is used to measure the pH of a given aqueous solution thereby determining the nature of the solution whether it is acidic or basic or neutral.
While using the pH meter or taking the measurement using the pH meter --
- it should be kept in a storage solution for effective working.
- Before using the device, it is rinsed with a deionized water and pat dry.
- Record the measurements when the pH meter stabilizes.
