Answer:

4.22

Explanation:

pH stands for potential hydrogen. The letter “p” denotes potential and the letter “H” denotes hydrogen.

pH helps to find the acidity or alkalinity of an aqueous solution.

The number of hydrogen ions (protons) present in a solution is determined by the pH scale.

A pH greater than 7 makes the water more alkaline and a pH less than 7 makes the water more acidic.

$pH=-\log [H^+]=-\log [0.00006]=4.22$

What is/are the product(s) of a neutralization reaction of a carboxylic acid? View Available Hint(s) What is/are the product(s)

lutik1710 [3]

Answer:

A carboxylate salt and water

Explanation:

A carboxylic acid is an organic compound that has general formula RCOOH, where R is a carbon chain. Because it's an acid, the neutralization will happen when it reacts with a base, such as NaOH.

When this reaction occurs, the base will dissociate in Na⁺ and OH⁻, and the acid will ionize in RCOO⁻ and H⁺, so the products will be RCOO⁻Na⁺ (a carboxylate salt) and H₂O (water).

Read the following chemical equation: Ti + 2Cl2 → TiCl4 Which statement best identifies and describes the reducing agent in the

goldenfox [79]

Answer: Ti is the reducing agent because it changes from 0 to +4 oxidation state.

Explanation:

Firstly, we need to identify the reducing agent and the oxidizing agent.

The reducing agent: is the agent that has been oxidized via losing electrons.

The oxidizing agent: is the agent that has been reduced via gaining electrons.

Here, Ti losses 4 electrons and its oxidation state is changed from 0 to +4 and Cl₂ gains one electron and its oxidation state is changed from 0 to -1.

So, Ti is the reducing agent because its oxidation state changes from 0 to +4.

Cl₂ is the oxidizing agent because its oxidation state changes from 0 to -1.

Thus, The right answer is Ti is the reducing agent because it changes from 0 to +4 oxidation state.

How many milliliters of 0. 0850 m naoh are required to titrate 25. 0 ml of 0. 0720 m hbr to the equivalence point?

charle [14.2K]

The volume of 0.0850 M NaOH is required to titrate 25.0 ml of 0.0720 M is 21.176 ml.

<h3>What are normality and molarity?</h3>

Normality is defined as the number of equivalents per litre of the solution

It is given by

Normality = number of equivalents / 1 L of solution

Molarity is defined as the number of moles of solute present in one litre of solution

Molarity = moles of solute / 1 litre of solution

Relationship between molarity and normality

Normality = Molarity × Acidity or Basicity of a salt

Here, the Acidity Of NaOH is 1 and the basicity of HBr is also 1.

Thus, Normality = Molarity

We know, N₁V₁ = N₂V₂

We can also write it as M₁V₁ = M₂V₂

V1 = $\frac{M_2V_2}{M_!}$

Substitute M₁ = 0.0850 M, M₂ = 0.0720 M, V₂= 25 ml

V1 = 21.176 ml

Hence, The volume of 0. 0850 m NaOH are required to titrate 25. 0 ml of 0. 0720 m is 21.176 ml.

Write differences between homogeneous mixture and heterogeneous mixture

Pie

Answer:

Homo means same

Hetero means different.

Homogeneous mixtures have one phase, it all looks the same, Fruit juice is homogeneous, solutions are homogeneous.

Heterogeneous mixtures have different phases, you can see the different parts, pepper is an example of a heterogeneous mixture.

A homogeneous mixture - Think Kool Aid (Completely Dissolved)
A heterogeneous mixture - Like pepper poured into a glass of milk.

In a homogeneous mixture the constituents are able to dissolve in each other due to their similar intermolecular forces, whereas in a heterogeneous mixture the constituents are not miscible- meaning they can't dissolve in each other.

To clarify: intermolecular forces describe the way that types of molecules will interact with each other. For instance, water (a polar molecule) and naphthalene (a non-polar molecule) are said to be "immiscible" because their intermolecular forces do not match. The saying goes: "like dissolves like". Meaning that molecules that have similar IFs will be mutually soluble (miscible, in other words).

Homogenous means the same all over...every cubic millimeter is about the same as every other one. Like water or soda.
Heterogenous means difference in places, like salsa, with slightly different chunks of stuff depending on where you dipped your chip.
