What pH is a weak alkali?
any concerted alkali is weak alkali
Is weak base on the pH scale is it 3?
A WEAK BASE on the pH scale would be , pH = 8 NB A WEAK ACID on the pH scale would be , pH = 6. The pH scale ranges from 0 to 14 . pH = 0 VERY STRONG ACID/ pH = 5 A weak Acid pH = 7 Neutrality ( Water) pH = 9 A Weak Alkali/Base pH = 14 VERY STRONG ALKALI/BASE. NB An Alkali is a soluble base.
What colour would a weak alkali turn in Universal Indicator?
A weak alkali would typically turn blue or purple in Universal Indicator, indicating a pH around 8-10.
What is colour of universal indicator be in weak alkali?
In weak alkali, universal indicator will typically turn green or blue. The specific color will depend on the pH of the solution - the higher the pH, the bluer the color.
Is the pH 10 an acid or alkali?
pH = 10 is a moderately strong ALKALI. The pH scale is ;- 1 - 6 ; Strong Acid to weak acid 7 ; water (neutrality) 8 - 14 ; Weak alkali to strong alkali. NB pH only ranges from '1' to '14'.

Is alkali an acid?
No. Alkali's and acids are an separate ends of the pH scale, the pH of acids being 1, 2, 3, 4 and 5 (strong to weak) and the pH of alkali's being 11, 12, 13, 14 and 15 (weak to strong). Examples of acids are hydrochloric acid (strong) and vinegar (weak). Toothpaste is an example of a weak alkali.
What is a pH of weak alkali?
A weak alkali typically has a pH above 7 but less than 10. Examples include baking soda (pH around 8.3) and household ammonia (pH around 10).

Is soap strong or weak alkali?
Moderate. It's pH can vary from 9,5 till 14.
Which colour does a strong alkali turn litmus paper?
ph 8- p14 is a alkali. blue for weak alkali (ph 8) purple for strong alkali (ph14)
Is banana an acid or an alkali?
The pH of a ripe banana is about 4.5 to 5.2, a weak acid.
Is is soap solution strong or weak acid?
its an alkali, the other side of the pH scale you numpty;)
