What is the hydroxide ion concentration of a solution that has a pH of 9.630?

Chemistry
1 answer:
Kobotan [32]3 years ago
7 0

Answer:

Which is the ph of a solution in which the concentration of hydroxide ion is greater than the concentration of hydrogen ion?

An acidic solution is one in which the hydrogen ion concentration is greater than the hydroxide ion concentration; in other words, the hydrogen ion concentration is greater than 1 X 10-7 M, and the hydroxide ion concentration is less than 1 X 10-7 M. In terms of pH, an acidic solution has a pH less than 7

What is Alkaline and Acid in full definition​
Harrizon [31]

Answer:

The solution is neither acidic or basic. An acid is a substance that donates hydrogen ions. ... Because the base "soaks up" hydrogen ions, the result is a solution with more hydroxide ions than hydrogen ions. This kind of solution is alkaline. Acidity and alkalinity are measured with a logarithmic scale called pH.

What is occurring when reactants are mixed and heated and liquid collects in the sidearm of the apparatus
olga55 [171]

When reactants are mixed and heated and liquid collects in the sidearm of the apparatus, a chemical reaction is occurring.

<h3>What is a chemical reaction?</h3>

A chemical reaction is said to occur when reactants are combined to form products. We must note that the formation of products is evidenced by;

  • Appearance of a liquid
  • Appearance of a gas
  • Appearance of a solid

Hence,  when reactants are mixed and heated and liquid collects in the sidearm of the apparatus, a chemical reaction is occurring.

A metal sample weighs 57.3g and has volume of 6.3mL what is the density of the sample
PilotLPTM [1.2K]

Answer:

<h2>9.10 g/mL</h2>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume} \\

From the question we have

density =  \frac{57.3}{6.3}  \\  = 9.095238...

We have the final answer as

<h2>9.10 g/mL</h2>

Hope this helps you

If an object is accelerating at a rate of 25 m/s2, how long (in seconds) will it take to reach a speed of 550 m/s? (Assume an in
V125BC [204]

Answer:

22s

Explanation:

Given parameters:

Acceleration  = 25m/s²

Final velocity = 550m/s

Initial velocity  = 0m/s

Unknown:

Time taken  = ?

Solution:

To solve this problem, we are going to use one of the motion equations:

                 v  = u + at

v is the final velocity

u is the initial velocity

a is the acceleration

t is the time taken

                  550 = 0 + 25 x t

                  550  = 25t

                    t  = 22s
