What is the hydrogen ion concentration of a solution with pH=8.25 ?
77julia77 [94]

Answer:

The answer is

<h2>5.62 \times  {10}^{ - 9} \:  M</h2>

Explanation:

The pH of a solution can be found by using the formula

pH =  -  log( {H}^{ + } )

where

{H}^{ + } is the hydrogen ion concentration of the solution

From the question

pH = 8.25

The hydrogen ion concentration of the solution is

8.25 =  -  log( {H}^{ + } )

<u>Find antilog of both sides</u>

That's

{H}^{ + }  =  {10}^{ - 8.25}  \\  = 5.62 \times  {10}^{ - 9} \:  M

We have the final answer as

5.62 \times  {10}^{ - 9} \:  M \\

Hope this helps you

Pressure of the gas inside the container is 662.59 torr.

<h3>What is ideal gas law?</h3>

The ideal gas law (PV = nRT) connects the macroscopic characteristics of ideal gases. An ideal gas is one in which the particles are both non-repellent and non-attractive to one another (have no volume).

The general law of ideal gas can be applied here: PV is equal to nRT, where P is the gas pressure in atm.

V is the number of moles of the gas in a mole, and n is the volume of the gas in L. R is the universal gas constant. T is the temperature(Kelvin) of the gas.

If P and T are different values and n and V are constants, then

(P₁T₂) = (P₂T₁).

P₁ = 735 torr, T₁ = 29°C + 273 = 302 K,

P₂ = ??? torr, ​T₂ = 62°C + 273 = 335 K.

∴ P₂ = (P₁T₂)/(P₁) = (735 torr)(302 K)/(335 K) = 662.59 torr.
