Determine the resulting pH when 12mL if 0.16M HCl are reacted with 32 mL if 0.24M KOH.

TEA [102]

Answer:

pH = 13.1

Explanation:

Hello there!

In this case, according to the given information, we can set up the following equation:

$HCl+KOH\rightarrow KCl+H_2O$

Thus, since there is 1:1 mole ratio of HCl to KOH, we can find the reacting moles as follows:

$n_{HCl}=0.012L*0.16mol/L=0.00192mol\\\\n_{KOH}=0.032L*0.24mol/L=0.00768mol$

Thus, since there are less moles of HCl, we calculate the remaining moles of KOH as follows:

$n_{KOH}=0.00768mol-0.00192mol=0.00576mol$

And the resulting concentration of KOH and OH ions as this is a strong base:

$[KOH]=[OH^-]=\frac{0.00576mol}{0.012L+0.032L}=0.131M$

And the resulting pH is:

$pH=14+log(0.131)\\\\pH=13.1$

Regards!

1. given 5 mols of the compound below what is the mol ratio between the compound and O? Ca_4Si_2O_6(CO_3)(OH)_2

Gre4nikov [31]

The mole ratio of the compound and its constituent elements are as follows:

The mole ratio between the compound and O is 5 : 22
The mole ratio between the compound and Si is 2 : 4
The mole ratio between the compound and Ca is 5 : 20
The mole ratio between the compound and C is 1 : 1

<h3>What is mole ratio?</h3>

Mole ratio is the ratio of the moles of one or more elements or compounds to another.

The given compound is Ca₄Si₂O₆(CO₃)(OH)₂

Moles of oxygen present in 1 mole of compound = 11 moles

Moles of Si present in 1 mole of compound = 2 moles

Moles of Ca present in 1 mole of compound = 4 moles

Moles of C present in 1 mole of compound = 1 mole

Given 5 moles of the compound below, the mole ratio between the compound and O is 5 : 22
Given 2 moles of the compound below, the mole ratio between the compound and Si is 2 : 4
Given 5 moles of the compound below, the mole ratio between the compound and Ca is 5 : 20
Given 3.5 moles of the compound below, the mole ratio between the compound and C is 1 : 1

Given the equation of the reaction below;

Pb(NO₃)₂ (aq) + 2 KI (aq) --> PbI₂ (s) + 2 KNO₃ (aq)

the mole ratio of the reactants and products are as follows:

Pb(NO₃)₂ : 2 KI (aq) = 1 : 2
Pb(NO₃)₂ : PbI₂ (s0 = 1 : 1
Pb(NO₃)₂ : 2 KNO₃ (aq) = 1 : 2

In conclusion, the mole ratio of reaction is the ratio in which moles of the substances combine.
