Besides water, what is the product of a Neutalization Reaction between HClO3 and Sr(OH)2?a. SrClO3
b. Sr-1(ClO3)+2
c. Sr2CIO3
d. Sr(ClO3)2

Answers

Answer:

The answer to your question is letter d. Sr(ClO₃)₂

Explanation:

Data

Reactants HClO₃ and Sr(OH)₂

This is a neutralization reaction because the reactants are a base (Sr(OH)₂) and an acid (HClO₃).

The products in a neutralization reaction are always water and a salt.

Balanced chemical reaction

Sr(OH)₂ + HClO₃ ⇒ H₂O + Sr(ClO₃)₂

Which solution when mixed with a drop of bromthymol blue will cause the indicator to change from blue to yellow 1) 0.1 M HCl. 2) 0.1 M CH3OH. 3) 0.1 M NH3. 4) 0.1 M NaOH

Answers

The solution that when mixed with a drop of bromthymol blue will change the indicator to yellow is A. 0.1 M HCl.

What is an indicator?

An indicator simply means a substance that has measurable and observable characteristics that is important to depict an acidic or alkaline substance.

In this case, the solution that when mixed with a drop of bromthymol blue will change the indicator to yellow is 0.1 M HCl.

The pH scale for acids and bases ranges from _____.A.) 1-7
B.) 0-14
C.) 1-14
D.) 1-12

Answers

The pH scale for acids and bases ranges from 1 - 14. The answer is letter C. The rest of the choices do not answered the question above. There are quite a few relationships between [H+] and [OH−] ions. And because there is a large range of number between 10 to 10-15 M, the pH is used. pH = -log[H+] and pOH = -log[OH−]. In aqueous solutions, [H+ ][OH- ] = 10-14. From here we can derive the values of each concentration.

-log[H+ ] + -log[OH- ] = -log[10-14]

pH + pOH = 14

So pH = 14 – pOH and pOH = 14 – pH

the correct answer is B.) 0-14
