Which is more dangerous acid or alkali?
Substances with pH values less than seven are acids, while numbers higher than seven are alkaline. The higher or lower the number, the more acidic or basic a substance is and the more damage it can cause. Alkali burns are the most dangerous.
What number is a weak alkali?

Is ammonia a strong alkali?
Ammonia is a typical weak base. Ammonia itself obviously doesn’t contain hydroxide ions, but it reacts with water to produce ammonium ions and hydroxide ions.
Can alkali dissolve things?
Alkalis. Alkalis are bases that dissolve in water. Common alkali-containing substances are lyes, ammonia, hair-relaxing agents, nonphosphate detergents, dishwasher soaps, and disk batteries. Lyes are alkaline agents that contain sodium hydroxide (NaOH), potassium hydroxide (KOH), or calcium hydroxide (Ca(OH)2).
How can you tell if an alkali is strong or weak?
The issue is similar with bases: a strong base is a base that is 100% ionized in solution. If it is less than 100% ionized in solution, it is a weak base. There are very few strong bases (see Table 12.2 “Strong Acids and Bases”); any base not listed is a weak base. All strong bases are OH – compounds.
What household items contain alkali?
Common household alkalis include indigestion tablets (antacids), bleach, toothpaste, baking powder, cream cleaner, oven cleaner, metal polish and alkaline batteries. Alkalis react with acids and neutralize them.
Is coffee alkaline or acidic?
With an average pH of 4.85 to 5.10, most coffees are considered rather acidic. While this doesn’t present a problem for most coffee lovers, the acidity can negatively affect certain health conditions in some people, such as acid reflux and IBS.
