Which base is the strongest?

Chemistry
2 answers:
slamgirl [31]3 years ago

Answer:

The strong base  is with H^+ concentration equals to 1 \times 10^{-12} M.

Explanation:

The pH of the solution is defined as negative logarithm of H^+ ions in a solution.Higher the H^+ ions concentration lower will be the value of pH and more acidic will be the solution.

pH=-\log[H^+]

1)[H+] = 1 \times 10^{-9} M

pH=-\log[1 \times 10^{-9} M]=9 Most acidic solution

2) [H+] = 1 \times 10^{-11} M

pH=-\log[1 \times 10^{11} M]=11

3) [H+] = 1 \times 10^{-10} M

pH=-\log[1 \times 10^{-10} M]=10

4)[H+] = 1 \times 10^{-12} M

pH=-\log[1 \times 10^{-12} M]=12 Most basic solution

Im assuming that 10-9, 10-10... is 10 to the power of 9 and 10 to the power of 10, respectively.

In the pH scale, acids are pH<7 and bases have pH>7. Each increase in pH makes something less acidic (or more basic) by 10.
Therefore [H+]=1x10^12 is the most basic

What volume of 1.10 M SrCl2 is needed to prepare 525 mL of 5.00 mM SrCl2?
grigory [225]

Answer:- 2.39 mL are required.

Solution:- It's a dilution problem and to solve this type of problems we use the dilution equation:

M_1V_1=M_2V_2

Where, M_1 and M_2 are molarities of concentrated and diluted solutions and V_1 and V_2 are their respective volumes.

M_1 = 1.10M

M_2 = 5.00mM = 0.005M    (since, mM stands for milli molar and M stands for molar. 1M = 1000mM)

V_1 = ?

V_2 = 525 mL

Let's plug in the given values in the formula:

1.10M(V_1)=0.005M(525mL)

V_1=(\frac{0.005M*525mL}{1.10M})

V_1=2.39mL

So, 2.39 mL of 1.10M are needed to make 525 mL of 5.00mM solution.

What is the molarity of a 5.0 L solution that contains 0.5 moles of KNO3
pashok25 [27]

Answer:

Molarity of a 5.0 L solution that contains 0.5 moles of KNO3 is 0.1 M

Explanation:

Molarity : It is used to express the concentration of the solution and defined as total moles of solute present in one liter of solution .

Molarity =\frac{moles\ of\ solute}{volume\ of\ solution(L)}

Moles of KNO3 = 0.5 (given)

Volume of solution = 5.0 L

Substitute the value in given formula ,

Molarity =\frac{0.5\ moles }{5.0\ L}

on calculation,

Molarity = 0.1 mol/L

Molarity = 0.1 M

(M = mol/L)
