What happens to the chemical reactivity of alkali metals as you increase atomic numbers?
The chemical reactivity of alkali metals increase when the atomic number increase.
How do you tell the strength of an acid or alkali?
you get a scale like this
What do you do if an acid or alkali is spilt?
If an acid or alkali is spilt you add the opposite to it of of equal strength.
What is indicat?
Universal indicator changes colour in acids and alkalis. Its colour shows the strength of an acid or alkali. strong acid= redweak acid= orange / yellowneutral= greenweak alkali= turquoise / bluestrong alkali= deep blue / purple The strength of an acid or alkali is shown on the pH scale of numbers.
What is an alkalimeter?
An alkalimeter is a device used for measuring the strength of an alkali.

Is alkali strong or weak?
Alkalis, bases, vary in strength as do acids
What do androstenedione supplements do?
Supplementation with androstenedione increases blood levels of testosterone, which among other things, will lead to an increase in strength and muscle mass.
What is the difference of litmus paper and a pH paper?
pH.paper tells the strength of an acid and alkali and litmus paper tells that whether the substance is an acid or an alkali.
Will the pH change when an alkali is added to an acid?
Yes. The pH will increase.
What colour an alkali comes out with a universal indicator?
Blue/Violet/Indigo . depending on the strength of the alkali. Water (neutral ) is green Acids ' Red/Orange/Yellow.
Why alkali metal density increase going down the group?
Atomic-volume of alkali metals increases down the group ,But increase in mass dominates over increase in volume ,since density=(mass)/(volume) ,density increases down the group
