This is an incomplete question, here is a complete question.
What are the concentrations of hydrogen ion and hydroxide ion in household ammonia, an aqueous solution of NH₃ that has a pH of 11.00?
Answer : The concentrations of hydrogen ion and hydroxide ion in household ammonia is, and
Explanation :
As we know that the aqueous solution of ammonia is ammonium hydroxide that is,
The equilibrium reaction will be:
Given:
pH = 11.00
First we have to calculate the hydrogen ion concentration.
pH : It is defined as the negative logarithm of hydrogen ion concentration.
Now we have to calculate the pOH.
Now we have to calculate the hydroxide ion concentration.
Therefore, the concentrations of hydrogen ion and hydroxide ion in household ammonia is, and
Answer:
HCHO₂(aq) + Na⁺(aq) + OH⁻(aq) ⟶ Na⁺(aq) + CHO₂⁻(aq) + H₂O(ℓ)
Explanation:
An ionic equation uses the symbols (aq) [aqueous] to indicate molecules and ions that are soluble in water, (s) [solid] to indicate insoluble solids, and (ℓ) to indicate substances (usually water) in the liquid state.
In this reaction, aqueous sodium hydroxide reacts with aqueous formic acid to form sodium formate and water.
1. Molecular equation
HCHO₂(aq) + NaOH(aq) ⟶ NaCHO₂(aq) + H₂O(ℓ)
2. Ionic equation
Sodium hydroxide and sodium formate are soluble ionic compounds, so we write them as hydrated ions.
HCHO₂(aq) + Na⁺(aq) + OH⁻(aq) ⟶ Na⁺(aq) + CHO₂⁻(aq) + H₂O(ℓ)
Answer: True
Explanation:
If you’ve seen a baseball game, you’ve probably also experienced the sight of a ball going up and up, until you begin to wonder when it’s going to come down! Yet every time, the ball does fall back to earth. Why? Gravity is an attractive force that exerts a pull between two objects, such as a baseball and the earth.
