What is the color code for electric blue?

Why the color of hyperlink is blue?
Sir Tim Berners-Lee (inventor of the web) made hyperlinks blue by chance. It's a fortunate color to choose because other colors such as green and red are troublesome for people with color-vision deficiencies (such as color-blindness).

WHAT IS THE BEST BACKGROUND COLOR?
It depends on the color scheme you choose for the website, but an off white is a very good safe choice for the background color for any website.
Which one of the following is the shorthand property used to set the border color for all sides of an element?
To set the border colour for all sides of an element, just use the border-color property. For instance, if you wanted the colour of the border on each side of an element to be blue, just put: border-color: blue;
What would be the color of cobalt chloride test paper be with a drop of ethanol?
The cobalt chloride test paper would turn from blue to pink when exposed to ethanol. This is because ethanol dehydrates the cobalt chloride, causing a change in color.
What is the color of ethanol flame during combustion?
Etanol is burning with a faint blue-ish flame color
What color is CoCl2-6H2O-ethanol?
The color of CoCl2-6H2O in ethanol solution is typically pink or rose-red. This color arises from the presence of the hydrated cobalt(II) ions in the complex.
What is color of ethyl alcohol when lighted?
When ethyl alcohol (ethanol) is lit, it typically burns with a pale blue flame. The flame may appear nearly colorless in bright light, but the blue hue is due to the complete combustion of ethanol, producing carbon dioxide and water vapor. The presence of impurities can sometimes alter the color of the flame, but pure ethanol generally produces this characteristic blue flame.
What colour does a universal indicator change to when it is mixed with ethanol?
A universal indicator changes to a greenish-blue color when mixed with ethanol.
What are examples of concentrated solution?
Examples: - concentrated solution of sulfuric acid - concentrated solution of nitric acid - concentrated solution of ethanol - concentrated solution of sugar (syrup) - concentrated solution of table salt
What are concentrations of solutions?
Examples: - concentrated solution of sulfuric acid - concentrated solution of nitric acid - concentrated solution of ethanol - concentrated solution of sugar (syrup) - concentrated solution of table salt
What are concentration of solution?
Examples: - concentrated solution of sulfuric acid - concentrated solution of nitric acid - concentrated solution of ethanol - concentrated solution of sugar (syrup) - concentrated solution of table salt
What happens when ethanol is heated in presence of concentrated H2SO4?
When ethanol is heated in the presence of concentrated H2SO4, it undergoes dehydration to form ethylene gas. This reaction follows an elimination mechanism where a water molecule is eliminated from ethanol to produce ethylene.
What are some Example of concentration?
Examples: - concentrated solution of sulfuric acid - concentrated solution of nitric acid - concentrated solution of ethanol - concentrated solution of sugar (syrup) - concentrated solution of table salt
What is the color of ethanol?
It is colourless.
What method is used to obtain a concentrated solution of ethanol from a dilute solution of ethanol dissolved in water?
To obtain a concentrated solution of ethanol from a dilute ethanol-water solution, distillation is commonly used. This process leverages the difference in boiling points between ethanol (approximately 78.4°C) and water (100°C). By heating the mixture, ethanol vaporizes first, allowing it to be collected and condensed back into liquid form, resulting in a higher concentration of ethanol. This method is efficient and widely employed in both laboratory and industrial settings.
