An aqueous solution contains 300 parts per million of KOH. Determine the number of grams of KOH present in 1000 grams of this so
PSYCHO15rus [73]
To determine the number of grams of potassium hydroxide, we need to know what is the units of parts per million and what it means. Then, we can multiply the grams of solution to obtain the grams KOH. Parts per million (ppm) means that there is 1 mass unit of solute per 1 million mass units of solution. Therefore, 

300 ppm = 300 g KOH / 1000000 g solution

mass KOH = 300 g KOH / 1000000 g solution (1000 g solution)
mass KOH = 0.3 g KOH

Methyl red is a common acid-base indicator. it has a ka equal to 6.3 × 10–6. its un-ionized form is red and its anionic form is
Maksim231197 [3]
Hello!

The pKa of an indicator tells us the pH where it changes color. The pKa of Methyl red is 

pKa=-log(Ka)=-log( 6,3*10^{-6} )=5,20

So, at a pH=7,8, Methyl Red would be at a pH over its pKa, so it would be in its basic form. The Basic Form of Methyl Red is Yellow, so the solution would be Yellow.

Have a nice day!
