Answer is: A) The solution turns blue litmus to red.

Sulfuric acid (H₂SO₄) is a strong acid, it means that the solution of sufuric acid is more acidic (pH<7) than water (pH = 7).

Chemical dissociation of sulfuric acid in water:  

H₂SO₄(aq) → 2H⁺(aq) + SO₄²⁻(aq).

When solution turns phenolphthalein pink, it means it is basic (pH>7).

Sulfuric acid has more hydrogen ions (H⁺) and less hydroxide ions (OH⁻) than water.

Discuss FOUR ways in which one's acceptance of responsibility can influence
andrew11 [14]

Answer:

being responsible is owing up to the possible

consequences of your decision whether it was right or wrong.

communication is a two way process in which there is a messenger and receiver

one of the ways by which a person could be responsible is by saying 'I'

in all the things he would say, instead of 'we'

for example , " We don't like the way you acted a while ago " , change it to i don't like tye way you acted a while ago.

here u r establishing ownership on the things you want to say to the person

Calculate the [ OH − ] and the pH of a solution with an [ H + ] = 0.090 M at 25 °C . [ OH − ] = M pH = Calculate the [ H + ] and
Valentin [98]

Answer:  a) [OH^-]=1.09\times 10^{-13} and pH = 1.04

b) [H^+]=1.02\times 10^{-11}  and pH=10.99

c) [H^+]=7.08\times 10^{-11} and [OH^-]=1.41\times 10^{-4}

Explanation:

pH or pOH is the measure of acidity or alkalinity of a solution.

pH is calculated by taking negative logarithm of hydrogen ion concentration.

pH=-\log [H^+]

pOH=-\log [OH^-]

pH+pOH=14

a) [H^+]=0.090M

pH=-\log [0.090]=1.04

pOH=14-1.04=12.96

12.96=-log[OH^-]

[OH^-]=1.09\times 10^{-13}

b) [OH^-]=0.00098M

pOH=-\log [0.00098]=3.01

pH=14-3.01=10.99

10.99=-log[H^+]

[H^+]=1.02\times 10^{-11}

c) pH=10.15

10.15=-\log [H^+]

[H^+]=7.08\times 10^{-11}

pOH=14-10.15=3.85

3.85=-log[OH^-]

[OH^-]=1.41\times 10^{-4}

You have dissolved 10 g sodium oxide in 200 ml water.calculate. the concentration of the solution​
mash [69]

0.05M is the concentration of the solution​.

The amount of a chemical substance in a mixture is expressed by the substance's concentration. Concentration can be expressed in numerous ways. In chemistry, the terms "solvent" and "solute" are used to denote the substance of interest and the medium in which it is dissolved, respectively

Subtract the solute's mass from the total volume of the solution. Using m as the solute's mass and V as the total volume of the solution, write out the equation C = m/V. To get the concentration of your solution, divide the mass and volume figures you discovered and plug them in.

C = m / V

C = 10 / 200

C = 0.05M.

Refer to the following illustration to answer this Question.
ad-work [718]

Answer:

Option (B) It separates the hydrogen ion (H+) from the chlorine ion (Cl–).

Explanation:

The reaction above simply illustrate the dissociation of HCl when dissolve is water.

When HCl is dissolved in H2O, it will separate into the hydrogen ion, H+ and chloride ion Cl- as shown below

HCl —> H+ + Cl-

The water help to separate the H+ from the Cl-
