What does adding alkali to acid do to pH?
The solution become more and more alkaline and the pH increase.
How do you convert an acid to a base?
Increase the hydroxide concentration in the acid by adding an excess of any alkali solution
What is a hydroxide solution a acid or alkali?
Alkali
Is ammonia solution acidic or alkali?
Alkaline!!!!
Why does the temperature decrease when there's more acid than alkali?
Because it is an exothermic reaction, meaning that heat is given off, and so the temperature of the solution decreases.

Why hydration enthalpy of alkali metal ion decrease with increase in atomic radii?
Li+ has maximum degree of hydration and for this reason lithium salts are mostly hydrated
Is it true that a ten-fold dilution of a strong acidic solution will decrease the pH by 1?
No, it is false. A ten-fold dilution of an acid will INCREASE the pH by 1 unit. Remember pH is 0-14 where 0 is most acidic. Diluting ten-fold on a logarithmic scale will increase the pH.Conversely, a ten-fold dilution of an alkali/base will increase the pH by 1 unit.
What happens to the chemical reactivity of alkali metals as you increase atomic numbers?
The chemical reactivity of alkali metals increase when the atomic number increase.
What lead to the increase in the strength of alkali?
What lead the increase in strength of alkali was to improve strength and reliability. Strengths and drying shrinkage is the reasons for the studies to improve alkali.
What is alkaline pottassium permanganate solution?
Alkaline potassium permanganate solution is a solution of potassium permanganate containing an alkali. The alkali can be sodium hydroxide or potassium hydroxide.
How do you explain when we add starch solution saliva dilute alkali and did not presence of starch and presence of glucose?
The enzyme amylase in the saliva broke the starch down into glucose.
Universal indicator is a solution that changes what in an acidic or alkali solution?
Universal indicator doesn't change anything in an acidic or alkali solution. All universal indicator does is show how acidic or alkaline a solution is (red being acidic, green being neutral and blue being alkali)
