What will be the outcome of putting litmus paper into bleach?

2 answers:

8 0

The correct answer is option C. The outcome of putting litmus paper into bleach would be that red paper turns blue, blue paper does not change. Domestic bleach is a strong base it typically has a pH of 11 to 13. So when testing for pH, it would really go with the basic characteristics.

Answer:

The correct option is c

Explanation:

The major ingredient in household bleach is sodium hypochlorite (NaClO). This compound is a base and the bleach solution assumes this alkalinity status.

A base is a substance that produces hydroxyl/hydroxide ion (OH⁻) as the only negative ion when dissolved in water. The pH of a base is between 7 to 14. One of the major properties of base is that it turns red litmus paper blue and it has no effect on blue litmus paper.

The pH of saliva is normally in the range of 6.4 to 7.0. However, when a person is ill, the person's saliva becomes more acidic.

aleksley [76]

Answer:

Concentration of hydrogen ion, $[H^+]=5.0118*10^{-6} M$

Explanation:

pH is defined as the negative logarithm of hydrogen ion's concentration.

The lower the value of pH, the higher the acidic the solution is.

The formula for pH can be written as:

$pH=-log[H^+]$

Given,

pH of the saliva of Marco = 5.3

To calculate: Hydrogen ion concentration in the saliva

Thus, applying in the formula as:

$pH=-log[H^+]$

$5.3=-log[H^+]$

So,

$log[H^+]=-5.3$

$[H^+]=10^{(-5.3)}$

$[H^+]=5.0118*10^{-6} M$

Reaction of HBr with 3-methylcyclohexene yields a mixture of four products cis-and trans-1-bromo-3-methylcyclohexane and cis-and

Umnica [9.8K]

Answer:

See explanation

Explanation:

The mechanism of this reaction including intermediates are shown in the image attached to this answer.

The reaction of HBr with 3-bromocyclohexene yields trans-1,2-dibromocyclohexane as the sole product because; the proton first attacks the 3-bromocyclohexene and a brominium ion is formed. This brominium ion is a cyclic intermediate as shown in the image attached.

Attack of a bromine ion afterwards must lead to the formation of trans-1,2-dibromocyclohexane as shown.

What would be considered the strongest base?

blondinia [14]

Answer:

A strong base is something like sodium hydroxide or potassium hydroxide which is fully ionic. You can think of the compound as being 100% split up into metal ions and hydroxide ions in solution.

Chemical properties of epoxide

Bas_tet [7]

Answer:

Epoxides, also called oxiranes, have a three-membered ring structure with one oxygen and two carbon atoms.

Epoxides can be formed from alkenes by reaction with peroxy acids (MCPBA for example).

Epoxides can be formed from halohydrin molecules by reaction with a base, which causes an intramolecular Williamson ether synthesis.

Explanation:

Epoxide, cyclic ether with a three-membered ring. The basic structure of an epoxide contains an oxygen atom attached to two adjacent carbon atoms of a hydrocarbon. The strain of the three-membered ring makes an epoxide much more reactive than a typical acyclic ether.
