NaOH is a strong base. What two ions do you expect to find in a solution of NaOH?

Chemistry

Marrrta [24]2 years ago
7 0

According to Arrhenius concept a base is one which can donate hydroxide ion in its aqueous solution.

Here NaOH is a base as it can donate OH-.

As NaOH is a strong base it will have very high dissociation constant.

Due to high dissociation constant if will almost completely dissociate into sodium ions and hydroxide ions.

NaOH  --> Na^{+}(aq)  + OH^{-}(aq)

Thus in a solution of NaOH we will expect  the following two ions

Na^{+}  + OH^{-}[/tex]

The most accurate measurement is 1.1 g. Option A

<h3>What is accuracy?</h3>

The term accuracy refers to the fact that the measurement is close to the true value. The closer the measurement is to the true value as given, the more accurate it is.

In this case, the true value of the mass of the  sample of calcium carbonate is 1.134 g. Now we have to look at all the masses of as obtained by Emma during the experiment.

The most accurate measurement is 1.1 g. Option A

Complete combustion of 3.20g of a hydrocarbon produced 9.69g of CO2 and 4.96g of H2O. What is the empirical formula for the hydr
vlabodo [156]

Let empirical formula for hydrocarbon is CxHy

it will undergo combustion as

CxHy + (x + y/4) O2  ---> xCO2 + (y/2 )H2O

Given that mass of CO2 produced = 9.69 g

So moles of CO2 produced = 9.69 / 44 = 0.22 moles

So moles of carbon present = 0.22 moles

mass of H2O produced = 4.96 g

Moles of H2O produced = mass / molar mass = 4.96 / 18 = 0.28 moles

So moles of H present = 2 X 0.28 = 0.56 moles

Let us divided the moles of each with lowest value of moles

Moles of Carbon = 0.22 / 0.22 = 1 moles

moles of H = 0.56 / 0.22 = 2.55

Multiplying with two to get whole number

the ratio of carbon and hydrogen will be : C:H = 2:5

empirical formula : C2H5
