An Erlenmeyer flask contains 25.00 mL of 0.10 M HCl. What is the pH of the solution?

Chemistry

Eduardwww [97]3 years ago

Answer:

The pH of the solution is 1.

Explanation:

Concentration of HCl solution = 0.10 M

HCl\rightarrow H^++Cl^-

1 mole of HCl gives 1 mole of H^+ ions.

[HCl]=[H^+]=0.10 M

The pH of the solution is defined as negative logarithm of H^+ ions in the solution.Mathematically written as

pH=-\log[H^+]

pH=-\log[0.10 M]=1

The pH of the solution is 1.

C=0.10 mol/l

pH=-lg[H⁺]

HCl = H⁺ + Cl⁻

pH=-lgc

pH=-lg0.10=1.0

pH=1.0

calculate the ph for each case in the titration of 50.0 ml of 0.130 m hclo(aq) with 0.130 m koh(aq). use the ionization constant
-BARSIC- [3]

The ph before the addition of any Koh is<u> 10.105.</u>

Concentration is the abundance of a constituent divided by way of the overall volume of an aggregate. several sorts of mathematical descriptions may be outstanding: mass concentration, molar concentration, variety concentration, and extent awareness.

After the addition of 50 ml KOH,

moles of KOH = 50 * 0.13 =<u> 6.5 mmol </u>

<u>moles </u><u>of HClO = 50 * 0.13 = 6.5 mmol </u>

occurred hydrolysis solution,

pH = 0.5(14 + pKa + log [base conjugate])

pH = 0.5(14 + (- log (4 * 10^-8)) + log (6.5/(50 + 50)))

pH = <u>10.105</u>

The concentration of a substance is the quantity of solute found in a given amount of solution. Concentrations are normally expressed in terms of molarity, defined because of the variety of moles of solute in 1 L of answer.

The Concentration of an answer is a measure of the quantity of solute that has been dissolved in a given amount of solvent or answer. A concentrated answer is one that has a rather huge quantity of dissolved solute.

What is the source of Earth's magnetic field according to what you have read in chapter 222
horsena [70]

Answer:

Scientists know that today the Earth's magnetic field is powered by the solidification of the planet's liquid iron core. The cooling and crystallization of the core stirs up the surrounding liquid iron, creating powerful electric currents that generate a magnetic field stretching far out into space.
