The pH of solution A is 2.4, while the pH of solution B is 9.4.

pishuonlain [190]

Answer:

The answer to your question is below

Step-by-step explanation:

pH definition

pH = - log [H⁺]

a) For pH = 2.4, solution A

2.4 = -log[H⁺]

[H⁺] = antilog⁻².⁴

[H⁺] = 0.00398

For pH = 9.4, solution B

[H⁺] = antilog⁻⁹.⁴

[H⁺] = 3.98 x 10⁻¹⁰

b) Divide hydrogen-ion concentration of solution A by hydrogen-ion concentration of solution B.

0.00398 / 3.98 x 10⁻¹⁰

10000000 times

c) By 7, because 7 is the number of zeros

What is the percent decrease from 60 to 39?

IrinaK [193]

X - the percent decrease

$60-60x=39 \ \ \ |-60 \\
-60x=-21 \ \ \ |\div (-60) \\
x=\frac{-21}{-60} \\ \Downarrow \\ x=\frac{-21}{-60}=\frac{-21 \div (-3)}{-60 \div (-3)}=\frac{7}{20}=\frac{7 \times 5}{20 \times 5}=\frac{35}{100}=35\%$

It's a 35% decrease.
