To measure the pH of 2% water !?! in any acid: try a pH meter, but be careful: you may damage the electrode!
In principle pH totally depends on WHAT kind of acid you are talking: You have know if it is weak or strong, what is the molecular mass, how many ionisable protons, and even the density (in g/L).

What makes up 98 percent of your solar system?
About 98 percent of the mass of the solar system is in the Sun.
Why is the sun the central body of the solar system?
Because about 98 percent of the mass of the entire Solar System is concentrated in the Sun, it has gravitational predominance and does the least relative movement - the planets and other objects orbiting around it.
How many percent of people have whorl as a fingerprint?
98%
Which planet has 98 percent carbon Dioxide?
Mars
Identify the number and kinds of atoms presented in ascorbic acid?
98
What is concentraction of concentrated sulfuric acid?
Industrial sulfuric acid has a concentration of about 98% by weight, the other 2% is water.
What percent oleum is sulfuric acid?
Oleum, also known as fuming sulfuric acid or pyrosulfuric acid, is a solution of sulfur trioxide (SO3) in concentrated sulfuric acid (H2SO4).
What you pH value when 100 percent sulfuric acid?
100% sulfuric acid rapidly decomposes until it reaches a concentration of 98%. This concentration is usually referred to as concentrated sulfuric acid. The pH value of 98% sulfuric acid is approximately -1.5 For comparison, sulfuric acid of this concentration has about 300 times as many active hydrogen ions as stomach acid (approximate pH 1).
Why the concentration of sulphuric acid should be maintained in 98 percent not in 100 percent in industries?
It will immensely cost to totally remove the impurities in sulfuric acid. For industrial purposes, they maintain a percentage value around 98%.
How do you make 25 percent sulfuric acid from 98 percent sulfuric acid?
Take 1 ml of 98% acid and add to 3 ml of water to get 25% acid. Total volume will be 4 ml (in this case). You can scale up this to any volume you need. (always add acid to water and not water to acid)
How do you prepare 1M sulfuric acid from concentrated sulfuric acid?
To prepare 1M sulphuric acid from concentrated sulphuric acid:First consider the molecular weight of H2SO4 = 98 g/mol, so you have to add 98g of conc. acid and make up to 1 liter of water (as pointed out at the 4thpoint).Considering that acid is a liquid, you should also consider density: where density = mass/volume, which is said on the bottle to be (about) 1.84 g/mL,so then you have: volume = 98g / 1.84(g/mL) = 53.2 mLNow you have to consider the acid purity, usually 98% then you have to do this: 53.2 mL if the acid were 100% pure convert in mL given with the purity of 98%, so 100% x 53.2 mL / 98% = 54.3 mL of (98%) concentrated acid.Finally CAREFULLY add this 54.3 mL (or 98 g, cf. first point) to about 0.9 L dist. water while continuously stirring (evolving heat!), and after that fill it up to 1.00 L with also dist. water. Never reverse this: DO NOT add water to concentrated fluids!
Descriptively what reaction is caused by mixing 98 percent concentration sulfuric acid 50 percent concentration caustic soda?
BOOM!
What is the difference between glacial acetic acid acetic acid?
Glacial acetic acid refers to Concentrated Acetic acid(98 - 100 %). Whereas, the term Acetic acid can refer to any concentrations(25% or 50% or any, even 100%).answ2. The addition of Glacial to the name refers to the fact that this concentrated material freezes (or appears to do so) at 16.5 deg C.
How do you get 98 to a percent?
.98 is 98 percent
What percent of 125 is 98 percent?
98 is 78.4 percent of 125 122.5 is 98 percent of 125
How many percent sulphuric acid in concentrated sulphuric acid?
sulphuric acid can be upto 78% concentrated >>>> Typically, "concentrated" acid can be upto around 98%. It can be taken to 100% however will fume and absorb water from the atmosphere if it can until it reaches around 98% again. Nitric acid is much lower - conc is usually just under 70% - beyond that it give off reddish gold gas (nitrogen dioxide) which is incredibly caustic to inhale (causes death by drowning upto two days later as the lungs dissolve and fill with fluid. Reason being nitrogen dioxide and water convert to concentrated nitric acid) Hydrochloric acid is lower still - around 33-35% beyond that it will fume of hydrogen chloride gas until the concentration reverts to around 33-35%. Unlike the other two acids mentioned above, hydrochloric will eventually evaporate away without trace - so is used for cleaning things like swimming pool surroundings - as once it has dried, there is no acid left.
What is the percent of 98?
percent of 98 = 9800%98= 98 * 100%= 9800%
