pH is a measure of the acidity or alkalinity of a solution. Solutions with a pH less than seven are considered acidic, while those with a pH greater than seven are considered basic (alkaline). pH 7 is considered neutral because it is the accepted pH of pure water at 25 °C, although, strictly, pure water cannot be assigned a pH value. pH is formally dependent upon the activity of hydrogen[1] ions (H+),[2] but for very pure dilute solutions, the molarity may be used as a substitute with some sacrifice of accuracy.[3] Because pH is dependent on activity, a property which cannot be measured easily or predicted theoretically, it is difficult to determine an accurate value for the pH of a solution. The pH reading of a solution is usually obtained by comparing unknown solutions to those of known pH, and there are several ways of doing this.

Weakly acidic. Anything below 7 is acidic, above being basic, 7 is neutral. pH 6.1 is an extremely weak acid, The pH scale is logarithmic so a small number change, ie. from 4 to 3 can mean big changes in acid strength.

A solution with a pH less than 7 is acidic but 6.1 is not strongly acidic. It is weakly acidic. pH more than 7 indicates basicity or alkalinity.

A pH of 7.0 is neutral. 6.1 is slightly acidic. The lower the number, the higher the acidity. Anything over 7.0 is a base. The higher the number, the stronger the alkalinity.

pH is a diploma of the acidity of a answer in terms of interest of hydrogen (H+). For dilute ideas, although, this is handy to alter the interest of the hydrogen ions with the molarity (mol/L) of the hydrogen ions (although, that may no longer unavoidably precise at greater concentrations Substance pH Battery acid 0.5 Gastric acid a million.5 – 2.0 Lemon juice 2.4 Cola 2.5 Vinegar 2.9 Orange or apple juice 3.5 Beer 4.5 Acid Rain <5.0 coffee 5.0 Tea or wholesome epidermis 5.5 Milk 6.5 organic water 7.0 wholesome human saliva 6.5 – 7.4 Blood 7.34 – 7.40 5 Sea water 8.0 Hand cleansing soap 9.0 – 10.0 kinfolk ammonia 11.5 Bleach 12.5 kinfolk lye 13.5

Buddy, it's weakly acidic. This is the most simplest chemistry. If you are having problems already, you better find a tutor, because it gets MUCH more complicated.

Basic

duuuhhh.. it's quite acidic.. and quite weak.... or just fine(for acidity)
the most acidic is in the left, 7 is alkaline or just alright(or basic perhaps) and after 7, it's basic.
4....5.....6.....7...8...9
