When an acid and an alkali react what is the pH?
If they react until neutral then the pH will be 7. However, if there is an excess of acid the pH will be <7 and vice versa.
What will happen to the pH of H2O if MgOH is dissolved in it?
The pH will go higher as MgOH (alkali) has a pH above 7. Also, the resulting solution will be more diluted. Hope this helps.
How do limestone quarries affect soil pH?
Limestones are generally of a pH anywhere between 7.5 to 8.6, so it would be alkali and probably neutralize the soil.
Is ammonia a strong acid or a strong base?
Ammonia is a weak basic (alkaline) with a pH of 11.5. Ammonia is weak because it only partially ionizes.

The answer to 'What pH would indicate and acidic soil?' is 5. 5 is a week number and 1 is the strongest, 7 is neutral and 14 is a strong alkali 9 is week.
What pH is a weak alkali?
Strong Acid ; pH = 1-3 Weak acid ; pH = 4-6 Neutral ; pH 7 Weak alkali ; pH = 8 -10 ( The answer) Strong Alkali ; pH = 11- 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.

Is acid worse than alkaline?
Both an acid and an alkali can be strong or weak. These are 2 different things. A strong acid is an acid which has a low pH (pH 1 or 2 or 3) and a weak acid is an acid of pH about 5 or 6. Whereas a strong alkali is an alkali of pH 11, 12 while a weak alkali has a pH of about 7 or 8.

Is pH 9 a strong or weak acid?
A pH of 9 is not acidic, it is basic. in order to be acidic the pH must be less than 7 It does not show whether the base is strong or weak as pH depends on both the strength of the acid/base as well as its concentration.
What is a pH scale How do you make a pH scale pls answer FAST?
its something used to see whether a substance is an acid or alkali. the scale is as follows 1-3 is a strong acid 4-6 is a weak acid 7 is neutral (distilled water) 8-9 is weak alkali 10-14 is a strong alkali
