What is the pH of a solution with a 3.2 x 10−6 M hydronium ion concentration?
Rainbow [258]

Answer:

<h2>5.49</h2>

Explanation:

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

pH = - log ([ { H_3O}^{+}])

H3O+ is the hydronium ion

From the question we have

pH =  -  log(3.2 \times  {10}^{ - 6} )  \\  = 5.49485..

We have the final answer as

<h3>5.49 </h3>

Hope this helps you

This is an ideal gas problem. The gas inside the balloon is considered ideal. Ideal gas equation is a function pressure, temperature, amount and volume. Note: amount is constant since the balloon ins closed. Pressure is maintained constant since the walls are flexible. Ideal gas equation is: PV=nRT. Put all constant in one side and variables in one. 

P/nR=T/V. To find the answer to the question equate the constants of both situation 
T1/V1=T2/V2
(25+273.15)/3=(x+273.15)/2
x=-74.38 degC
