Question

Guys help plss ssssssssss​

Answer 1

PH values of different mixtures:-

$\boxed {\begin{array}{c|c|c}\sf \underline {Mixture} &\sf \underline {pH\:value} & \sf \underline {Type \:of\;mixture} \\ &&\\ &&\\ \sf Lemon\:Juice & \sf 2.2-2.4 &\sf Acidic \\ &&\\ \sf Mixed \:Drink &\sf 6.0 &\sf Acidic \\&&\\ \sf Carrot\:Juice &\sf 6.9 &\sf Acidic \\ &&\\ \sf Saliva &\sf 7.4 &\sf Basic \\ \sf (Before\;meal) && \\ &&\\\sf Saliva & \sf 5.8 &\sf Acidic \\ \sf (After\:meal) &&\\ &&\\ \sf Coffee &\sf 4.5-5.5 &\sf Acidic \\ &&\\ \sf Tomato\:Juice & \sf 4.0-4.4 & \sf Acidic \end {array}}$

pH scale:-

• pH scale is a universal indicator .
• It is used to determine the concentration of Hydrogen ion $\sf (H_3O ^+)$ in a mixture.
• The letter p of the word pH is taken from the German word 'Potenz' .Potenz means power .

How to use:-

• We can determine the pH of a mixture from 0 to 14 .
• 0 means highly acidic .
• 14 Means highly basic .
• If the concentration of Hydrogen ion stay higher then the pH value will be low.
• If pH value is under 7 then the mixture is acidic.
• If pH value is over 7 then the mixture is basic
• pH=7 means neutral mixture.
