Answer : The correct options is, (A) The acidity of a solution.

Explanation :

pH meter : It is a type of instrument which measures the activity of hydrogen ion in water based solution.

Or, pH measure the acidity or alkalinity of the solution.

Or we can say that, it will provide the most direct measure of pH by measuring the hydrogen ion concentration of a solution.

The pH range is, 1 to 14.

When the value of pH is less then 7 then the solution will be acidic.

When the value of pH is more then 7 then the solution will be basic.

When the value of pH is equal to 7 then the solution will be neutral.

Hence, the correct options is, (A) The acidity of a solution.

3 elements that have similar properties

qwelly [4]

Answer:The elements in the first column of the Periodic Table (other than hydrogen) are known as Group 1A metals, or alkali metals. When you compare the chemical properties of these elements (lithium, sodium, potassium, rubidium, cesium, and francium), what you'll notice is that they are all remarkably similar.

8.) If 396 g of Carbon Dioxide (CO2) are produced, what mass of Oxygen

KengaRu [80]

Answer:

480 g of oxygen.

Explanation:

C3H8 + 5O2 ---> 3CO2 + 4H2O

Using the molar masses:

3*12 + 6*16 g of CO2 were formed from 10*16 g O2

132g g CO2 from 160 g O2

1g CO2 from (160/132) g O2

396 g from (160/132) * 396

= 480 g of oxygen.

The ionization constant of lactic acid ch3ch(oh) co2h am acid found in the blood after strenuous exercise is 1.36×10^-4 If 20.0g

lana66690 [7]

Answer:

Explanation:

CH₃CHOHCOOH ⇄ CH₃CHOHCOO⁻ + H⁺

ionisation constant = 1.36 x 10⁻⁴ .

molecular weight of lactic acid = 90 g

moles of acid used = 20 / 90

= .2222

it is dissolved in one litre so molar concentration of lactic acid formed

C = .2222M

Let n be the fraction of moles ionised

CH₃CHOHCOOH ⇄ CH₃CHOHCOO⁻ + H⁺

C - nC nC nC

By definition of ionisation constant Ka

Ka = nC x nC / C - nC

= n²C ( neglecting n in the denominator )

n² x .2222 = 1.36 x 10⁻⁴

n = 2.47 x 10⁻²

nC = 2.47 x 10⁻² x .2222

= 5.5 x 10⁻³

So concentration of hydrogen or hydronium ion = 5.5 x 10⁻³ g ion per litre .
