Answer:

The pH of a solution that has a pOH of 12.42 is 1.58

Explanation:

Step 1: Data given

At a temperature of 25.0 °C the pOH = 12.42

pH + pOH = 14

Step 2: Calculate the pH

pH + pOH = 14

pH = 14.00- pOH

pH = 14.00 - 12.42

pH = 1.58

The pH of a solution that has a pOH of 12.42 is 1.58

Answer:

pH=1.58

Explanation:

As we know that

pH+pOH=14

Given that pOH=12.42

we get pH=14-pOH

or pH=14-12.42

or pH=1.58

Potassium permanganate, KMnO, and glycerin, C3H5(OH)3, react explosively according to the
Finger [1]

The volume of CO2 at STP =124.298 L

<h3>Further explanation</h3>

Given

Reaction

4 KMnO4, +4 C3H5(OH)5, -7K2CO3, + 7 Mn2O3, +5 CO2, + 16 H2O

701,52 g of KMnO4

Required

volume of CO2 at STP

Solution

mol KMnO4 (MW=158,034 g/mol) :

mol = mass : MW

mol = 701.52 : 158.034

mol = 4.439

mol CO2 from equation : 5/4 x mol KMnO4 = 5/4 x 4.439 = 5.549

At STP 1 mol = 22.4 L, so for 5.549 moles :

=5.549 x 22.4

=124.298 L
