Acids generally have a pH ranging from 1 - 6.
pH 1 being the most acidic, and pH 6 being the least acidic.
eg, hydrochloric acid, nitric aicd, sulfuric acid has a pH of 1.
Ethanoic acid has a pH of 3.
Acids do not have a pH greater than 7. When the pH is greater than 7, this makes it a base.
they use the pH scale
Purified water should have a pH level of 7. The values of 7 is neutral on the pH scale.
Normally term,'PH' of a solution is used determine the strength of an acid which is nothing but the concentration of H+ ion concentration in a solution. ph= -log[H+] concentration.... since its -ve log hence smaller value of PH means it's more strong acid. ph=7 is value of water which is neutral. pH ranging below 7 are acids & above 7 are bases.
All alkalis have a bitter taste, turn red litmus paper blue, are good conductors of electricity, have pH values more than 7 and react with ammonium compounds to form ammonia gas. they also react with acids to form salt and water only. some common examples in our daily life cleaning products, detergents, soaps, toothpaste and etc. posted by: taimoor infrared
Acids have pH values below 7.0. Bases have values above 7.0.
Concentrated and dilute acids will give different pH values
Alkalis (bases) react with acids to neutralize them, so in one sense, they can be considered as "opposite" of acids. Bases produce pH values >7 and acids produce pH values <7.
pH is a measure of the concentration of hydrogen ions in a solution, with lower pH values indicating higher acidity and higher pH values indicating higher alkalinity. Acids have pH values below 7, while bases have pH values above 7. Acids release hydrogen ions in water, lowering pH, while bases release hydroxide ions, raising pH.
Acids and bases are described in the pH scale based on their strength. For instance,lactic acid has pH 6,but curd,obtained from milk itself has pH 3! HCl is called as the "king of acids" with pH 1. {on the pH scale,if any substance has pH 7, its considered acidic, while anything above 7 is basic.} Acids or Bases can be considered as acidic or basic by the colour changes in the pH scale{eg:red to orange[neutral]to violet}.
The strength of an acid or base is typically measured using the pH scale. Acids have a pH below 7, with lower pH values indicating stronger acids. Bases have a pH above 7, with higher pH values indicating stronger bases.
Acids have a pH under 7 and bases a pH over 7.
The pH scale is a measure of the acidity or basicity of a solution. It ranges from 0 to 14, with 7 being neutral. Acids have pH values below 7, bases have pH values above 7.
The pH level of an acid is less than 7 (neutral). Very strong acids will be around pH 1 and 2.
Different acids have different pH levels. The pH scale is a measure of acidity of any substance; a pH of 7 is neutral, anything with a pH lower than 7 is acidic. For example: lemons pH is about 2.2
The pH of diluted carboxylic acids can vary depending on the specific acid and its concentration. Carboxylic acids typically have pH values in the range of 2 to 5 when diluted in water. The presence of the carboxyl group (COOH) in carboxylic acids causes them to be weak acids, leading to slightly acidic pH values when diluted.
