the ph of a solution of HCl in water is found to be 2.50. what volume of water would you add to 1.00L of this solution to raise
morpeh [17]

<u>Answer:</u>

<em>To raise the pH of the solution to 3.10 we have to add 2.34 L of water.</em>

<u>Explanation:</u>

<em>Given that the pH of the solution of HCl in water is 2.5.</em>  Here the solution’s pH is changing from 2.5 to 3.10 which means the acidic nature of the solution is decreasing here on dilution. [H^+] ions contribute to a solution’s acidic nature and [OH^-]contribute to a solution’s basic nature.

The equation connecting the concentration of [H^+] and pH of a solution is pH= -log[H^+]

<em>[H^+]= 10^(^-^p^H^)[H^+]= 10^(^-^2^.^5^)=0.00316</em>

<em>When the pH is 3.1 [H^+ ]= 10^(^-^3^.^1^)=0.000794</em>

<em>On dilution the concentration of a solution decreases and volume increases.</em>

<em>M_1 V_1 = M_2 V_2</em>

<em>0.00316 \times 1 = 0.000794 \times V_2</em>

<em>V_2 = \frac{(0.00316 \times 1)}{0.000794} =3.24</em>

<em>Volume of water to be added =3.24-1</em>

<em>=2.24L</em>

A reaction proceeds with 2.72 moles of magnesium chlorate and 3.14 moles of sodium hydroxide. this is the equation of the reacti
den301095 [7]

The theoretical amount of each product obtained are:

  • 1.57 moles of Mg(OH)₂
  • 3.14 moles of NaClO₃

<h3>Balanced equation</h3>

Mg(ClO₃)₂ + 2NaOH —> Mg(OH)₂ + 2NaClO₃

<h3>How to determine the limiting reactant</h3>

From the balanced equation above,

1 mole of Mg(ClO₃)₂ reacted with 2 moles of NaOH

Therefore,

2.72 moles of Mg(ClO₃)₂ will react with = 2.72 × 2 = 5.44 moles of NaOH

From the calculation above, we can see that a higher amount (5.44 moles) of NaOH than what was given (3.14 moles) is needed to react completely with 2.72 moles of Mg(ClO₃)₂

Therefore, NaOH is the limiting reactant

<h3>How to determine the theoretical yield of Mg(OH)₂</h3>

From the balanced equation above,

2 moles of NaOH reacted to produce 1 mole of Mg(OH)₂

Therefore,

3.14 moles of NaOH will react to produce = 3.14 / 2 = 1.57 moles of Mg(OH)₂

Thus, the theoretical yield of Mg(OH)₂ is 1.57 moles

<h3>How to determine the theoretical yield of NaClO₃</h3>

From the balanced equation above,

2 moles of NaOH reacted to produce 2 mole of NaClO₃

Therefore,

3.14 moles of NaOH will also react to produce 3.14 moles of NaClO₃

Thus, the theoretical yield of NaClO₃ is 3.14 moles

Answer:

Embryonic stem cells are pluripotent, meaning they can give rise to every cell type in the fully formed body, but not the placenta and umbilical cord. ... Human embryonic stem cells have been derived primarily from blastocysts created by in vitro fertilization (IVF) for assisted reproduction that were no longer needed
