Define an Arrhenius base and describe properties of bases. Use an example to explain how an Arrhenius base will behave in water.

frozen [14]

An Arrhenius base is a molecule that when dissolved in water will break down to yield an $OH^-$ or hydroxide ion in solution.

<h3>What is Arrhenius base?</h3>

An Arrhenius base is a compound that increases the $OH^-$ ion concentration in aqueous solution.

An Arrhenius base is a substance that, when dissolved in an aqueous solution, increases the concentration of hydroxide, or , $OH^-$ ions in the solution.

Bases Properties

Arrhenius bases that are soluble in water can conduct electricity.

Bases often have a bitter taste and are found in foods less frequently than acids. Many bases, like soaps, are slippery to the touch.

Bases also change the colour of indicators. Red litmus turns blue in the presence of a base (see figure below), while phenolphthalein turns pink.

Some bases react with metals to produce hydrogen gas.

Acids (pH < 7.0) react with bases (pH > 7.0) to produce a salt and water. When equal moles of an acid and a base are combined, the acid is neutralized by the base. The resulting mixture will have a more neutral pH.

An Arrhenius acid is a substance that dissociates in water to form hydrogen ions or protons. In other words, it increases the number of $H^+$ ions in the water. In contrast, an Arrhenius base dissociates in water to form hydroxide ions $OH^-$ .

Example, sodium hydroxide, is added to an aqueous solution. NaOH dissociates into sodium, $Na^+$ , and hydroxide, $OH^-$ ions.

Explain how you can use boyle's law to determine the new volume of gas when its pressure is increased from 270 kPa to 540 kPa? T

LUCKY_DIMON [66]

There are several information's already given in the question. Based on the information's the answer can be easily deduced.

We know the formula

<span>P1*V1/T1 = P2*V2/T2
</span>
As the temperature is constant, so T1 and T2 can be negated. The formula changes to
<span>P1*V1 = P2*V2
</span>70 * 1 = 540 * V2
270/540 = V2
<span>V2 = 0.5
</span>
From the above deduction, we can conclude that the new volume is 0.5 liters. I hope that the procedure is clear enough for you to understand.

Which color in the rainbow has the longest wavelength? 1. orange 2. blue3. yellow4.green 5. red

rodikova [14]

In rainbow, the color that has the longest wavelength is red which means option 5 is the correct choice.

Dispersion is described to be the spreading of white mild into its complete spectrum of colors, in truth we also can say a complete spectrum of wavelengths. The white mild turns into from solar and includes seven colors. On one end of the spectrum is red with the longest wavelength. Blue or violet mild has the shortest wavelength. White mild is a aggregate of all hues withinside the color spectrum. The colors of the rainbow are: Red, orange, yellow, green, blue, indigo, violet.

Therefore, option 5 is the correct choice.
