Affective in doing what ...... ? Rephrase the question please.
you get a scale like this
For an acid, the solution remains colourless or unchanged. For an alkali, it would turn fuschia.
Sodium is an alkali metal.
The alkali metal with the largest electronegativity is fluorine, found in Group 1 of the periodic table. Its low atomic size and high effective nuclear charge lead to a strong attraction for electrons, resulting in the highest electronegativity among alkali metals.
Test the pH.
Well it is sodium hydroxide that is found in toothpaste.This is the simplest answer you could ever find
Sodium carbonate is a common alkali found in dishwasher tablets. It helps to break down food particles and grease on dishes by increasing the pH of the water, making it more effective in cleaning.
This location indicate that francium is an alkali metal, very reactive.
An alkali is a soluble base. Therefore, alkaline solutions are sources of hydroxide ions, OH- . A base is a proton acceptor, so the alkaline solution will neutralise an acid.
Yes, it is. You can tell weather something is an Alkali, Neutral pr acid via the pH scale or, you can tell if something is an alkali from its consistency; if it is sludgy (like washing-up liquid), it is an alkali. So, I am under the influence that washing-up POWDER is too, an alkali.J.S.P. Aged 11
An indicator, for example Litmus.
Lithium hydroxide is the strongest alkali in the alkali metal group.
